ORAFOL Fresnel Optics GmbH offers a wide variety of microstructured optical components in varios sizes. Among others fresnel prisms, cylindrical lenses and beamsplitters, lenticular lenses and corner cube reflectors. We provide both a catalogue of standard products that can be adapted to our customers' requirements as well as the capabilities to design and manufacture custom optical solutions including finishing processes e.g. anti-reflective coatings and nano-structures and precise CNC machining.

Surface relief diffusive microstructures (SRDM) are used for specifically distributing light in a defined angle range. They homogenize irregular light distributions as well as local intensity peaks. It is also possible to apply those diffusive microstructures directly into the plano side of all our plastic optics components. Our products will be precily trimmed to our customers requirements.

Microlens arrays are one- or two dimensional periodic patterns of small lens structures (lens dimensions up to a few millimetres). They can be used in a variety of ways, e.g. collimation or homogenization of light, depending on the design. We offer custom designs for our customers without limitations regarding the pattern in a wide range of lens sizes and overall array sizes. It is also possible to apply a microlens array directly into the plano side of all our plastic optics components. Our products can be finished with a range of optical coatings and nanostructures and will be trimmed precisely to our customers requirements.

The best known microstructured optic is the Fresnel lens. Compared to a standard lens the surface of the fresnel lens is divided into a number of concentric grooves allowing for a wide range of optical effects (e.g. high-aperture (fast) large-area) while also reducing thickness, weight and cost. Fresnel lenses can be designed as a collimator, collector or with finite conjugates. They are usually corrected for spherical aberration. We offer a variety of standard designs as well as custom designs for our customers. Our lenses can be finished with a range of optical coatings and nanostructures and will be trimmed precisely to our customers requirements.

Any device is only as reliable as the sum of its components. With more than fifteen years of experience in manufacturing tuned and detuned filter reactors for power factor correction, we are now offering our range of line reactors for application in power electronics. Same as with our capacitors, we focus on minimized power losses and maximum durability of the reactor – optimized for your application. Made of high-class transformer sheets and copper wire or aluminium band. Vacuum-impregnated with environmentally friendly, low-styrole resin for long operating life, high voltage strength and low noise levels. Standard terminals: copper terminal lugs, optional with screw-terminal blocks or cables. Integrated reversible thermal switch for monitoring of the reactor and control of external disconnection in case of overheating. Our standard range covers 400V 50Hz up to 300A per phase. Other values are available on request.

A consumer whose load includes a high proportion of variable speed motor drives and/or other harmonic generating loads may require a detuned capacitor system. This would perform the function of power factor improvement whilst preventing any amplification of harmonic currents and voltages caused by resonance between capacitors and inductances in the mains. Our low-loss reactors are designed for such systems. They are available with adjusted (Dla) and fixed ratings (D): The adjusted reactor is designed to create exactly the required output of reactive power, allowing for the internal voltage rise inside the resonating circuit formed together with the capacitor connected in the circuit. Note that exact sizing of the capacitor is necessary.

Harmonic distortion is a key issue not only in low voltage, but also medium and high voltage Power Factor Correction. The installation of detuning reactors helps to protect capacitor installations from dangerous and devastating resonances by preventing any amplification of harmonic currents and voltages caused by resonance between capacitors and inductances in the mains. At the same time, it reduces the overall level of harmonic distortion in the mains. With FKD-MVTM, we are now expanding our long-year experience in making reactors for low-voltage PFC to the field of medium voltage up to 10kV. The low-loss reactors which are made of aluminium windings on iron cores, are optimized for use with our MSDTM capacitors. Each reactor is formed by a set of three compactly sized single phase units; that makes handling easier during mounting and maintenance and opens interesting options for allocation and dimensioning of your equipment.

The PK16™ capacitor can be universally used for the assembly of low inductance DC buffer circuits and DC filters; with its high energy density it can replace banks of series-connected electrolytic capacitors as well as large film capacitors in rectangular cases. The capacitance in a DC buffer circuit must be sufficiently sized to both handle and smoothen the occurring ripple currents. The traditional use of series-/parallel-connected electrolytic capacitors offered large capacitance at seemingly low cost, however the low cost per microfarad is countered by the very low current strengh, the high sensitivity to voltage and current surges, as well as a substantial risk of failures in the field, resulting in high maintenance cost. Our advanced know-how in special capacitor film coating and many years of practical experience in designing and manufacturing capacitors have allowed us to develop our PK16™ range with high capacitance density.

In power electronics in general, and especially in low inductance buffer circuits with higher voltages as well as in discharge circuits, the call for capacitors with low inductance tends to pose problems: traditional high voltage capacitors are filled with oil, and the generous bushings required for clearance and creepage as well as internal safety mechanisms add substantially to the self-inductance of the capacitor. Based on decades of proprietary experience in metallizing capacitor films, ELECTRONICON has created a range of high voltage capacitors in self-healing technology, using the opportunities of special metallizing patterns. Despite the high voltage rating, our E51 range is manufactured in dry technology and without expensive bushings. Inside the can made of self-extinguishing plastic, the capacitor element is enclosed in solid resin (PUR). Connection is made through robust flat terminals with internal thread.

E53 and E55 capacitors have a particularly low series resistance and high pulse strength. Using sophisticated metallizing patterns, our SINECUT slitting technology and clever winding geometries, they are especially suited for the damping of GTO thyristors and low-inductance buffer circuits with high rms currents. Along with their very good ratio of capacitance to volume, these components do also have very good self-healing characteristics without loss of capacitance. Their very low self-inductance makes them suitable for use in high-current applications with medium frequencies. The capacitors of the E53 product family are housed in flame-retardant plastic cans (V0) and filled with solid resin. Special care has been taken both in terms of design and conservative electrical rating to ensure reliable operation even under tough environmental conditions. Connection is usually made through robust axial terminals with internal thread.

AC capacitors require a hermetical casing in order to operate safely and without processes of chemical corrosion. The latter would result in deterioration of metal coating, decrease of capacitance as well as rise of loss factor and – consequentially – failure of the capacitor. DC capacitors – even though less sensitive to humidity – may suffer from excessive operating conditions as well. Another serious issue is the operation in conditions of extreme heat, and there are situations where placement in a cooling liquid is the only way. Certain high voltage applications may require the immersion of all components in insulation oil, such as MIDEL. Quite a few cooling or insulation oils behave aggressively towards metallized polypropylene, causing swelling of the film and deterioration of the contact layers. They must therefore be kept away from the capacitor elements. In the past, mostly MKV capacitors (with oil-impregnated paper electrodes) had to be used in such situations.

It works - even in your smaller DC links! A few years ago, our PK16TM pioneered the large-scale shift from batteries of electrolytic DC link capacitors to energy-efficient and highly reliable film capacitors which has become so common nowadays. The E61 range makes the benefits of this substitution available for DC links with smaller powers now. With their pin terminals, these capacitors can be integrated directly into your printed circuit board. The capacitors of the E61 series are optimized for high rms and surge currents. Along with their high specific ratio of capacitance to volume, they offer long-term stability and storability, as well as excellent self-healing without loss of capacitance. It is our advanced know-how in special capacitor film coating, combined with many decades of practical experience in designing and manufacturing capacitors, which have allowed us to develop this range with its numerous advantages over traditional electrolytic capacitors:

In modern applications of power electronics, AC capacitors are among the most critical links in the chain of components when it comes to long operating life, safety and reliability of operation. Decades of proprietary ELECTRONICON experience in metallizing capacitor films and designing high-end capacitors have created our very own Know-How, for instance in special metallizing patterns, our SINECUT slitting technology and optimized winding geometries. This enables us to design AC capacitors with a high specific ratio of capacitance to volume, high AC-voltage load capacity and outstanding suitability for high rms and surge currents. The cylindrical capacitors of our universal AC/DC series "E62" are perfect for non-sinusoidal voltages and pulsed currents, e.g. as damping or commutation capacitors switched in parallel to a thyristor, or connected in series with a resistor (damping of undesirable voltage spikes during the switching of power semiconductors).

The E62-3ph capacitors stand out by their high AC-voltage load capacity. They have been designed especially for heavy duty operation in extreme or sophisticated operating conditions, such as AC filtering and power factor correction in wind power and UPS applications, harmonic filtering in three-phase mains with high or unusual levels of harmonic distortion, a.m.o. Thanks to their construction, they have a very low series resistance and a small self-inductance. Our basic design principle - preferring short winding elements with comparably large diameters - as well as the use of wavecut technology in many models, serves for high rms and surge current strength. The three capacitor elements are connected in delta internally; the plant oil filling is environmentally friendly and serves for optimized heat dissipation and improved internal insulation.

The special kind of films and coating patterns used in our oil-filled E63-capacitors give them a high specific ratio of capacitance to volume and makes them extremely overvoltage proof. Very good self-healing characteristics and the integrated overpressure protection (" BAM ") ensure safe operation and controlled disconnection in the event of overload or failure at the end of operating life. Hence the E63s are interesting particularly for applications with high AC ripple currents, e.g. as smoothing or supporting capacitors in buffer storage circuits, in sensitive environment with high safety requirements. Note that the presence of an overpressure mechanism adds substantially to the self-inductance of the capacitor, and limits the surge current rating. If self-inductance and surge current are important issues, then our E50 or E53 ranges may be considered as a more adequate option.

Our capacitors of the E12 and E33 series are universally-suited for lighting and motor applications as well as power factor correction and power electronics. Their winding element of self-healing polypropylene film is immersed in eco-friendly vegetable oil and designed for highest requirements regarding operational life and functional safety even at high operating temperatures and other extreme conditions such as high humidity. Connection is made through tab connectors. The hermetical aluminium can is provided with an integrated overpressure safety mechanism (break-action mechanism, " BAM ") that disconnects the capacitor irreversibly from the supply in the event of a failure. The E12/E33 ranges comply with the "Type B" classification under lighting standard IEC/EN61048 as well as with "Class P2" under motor capacitor standard IEC/EN 60252-1. Please mind our safety remarks on the use of lighting capacitors in critical environment.

E57 are designed to fit directly to the terminals of your IGBT. Our range comprises standard as well as custom-tailored solutions which can be adapted to the specific geometrical and electrical requirements of your application environment. Connection is made through low-inductance copper bars which may vary in number, size and position according to your specifications. The UL:V0 plastic case houses compact and stable cylindrical windings, connected in parallel for maximum current strength and lowest possible selfinductance; it is filled with polyurethane resin, covered by a layer of UL94:V0 compliant resin protecting the winding package from humidity. Our highly reliable SecuMet™ film guarantees secure self-healing properties even under the most demanding operating conditions. Some of our E57 capacitors can be operated at ambient temperatures up to 105°C and are therefore suitable for usage in automotive and other critical applications

The traditional ALLFILM system of conventional medium and high voltage capacitors consists of aluminium foil and polypropylene, immersed completely in synthetic, flammable oil. Breakdowns in this kind of dielectric tend to result in permanent short circuits which take out the entire capacitor element, change the voltage conditions inside the capacitor and initiate a chain reaction of further failures of capacitor elements which will end up in the loss of the entire capacitor. In three-phase capacitors, this process is usually accompanied by the occurrence of phase asymmetries which may cause damage and catastrophic failure. In our MSD™ medium voltage capacitors, we are using the metallised polypropylene so well known from LV power factor correction. Instead of flat pack windings, our capacitance is formed by compact cylindrical windings, avoiding the mechanical stress at the edges of the ALLFILM flat packs.
