KO can offer Metallic Neutral Density Filters for use in Photographic Applications. We supply a range of Metallic Neutral Density (ND) Filters for a variety of applications – all individually QA checked and metrology tested for quality to ensure parts meet customers’ specifications. What’s more, our Metallic ND Filters are supplied in a range of sizes and shapes with custom coatings tailored to meet your individual applications. Our Metallic ND Filters reflect (with a metallic coating) light neutrally over a wavelength range (typically visual). They can be used to lower the intensity of light prior to the image plane. These are often used in photography, allowing photographers more flexibility with their setups to achieve desired effects. Often, an ND filter will be used in conjunction with a long exposure to prevent washed-out and overexposed images. They can also be used to add motion blur, reduce depth of field and to use a wider aperture. For more information read PDF…

Knight Optical can offer Circular Sheet Polariser for use within Photographic Applications. We supply a range of Circular Sheet Polariser for a range of applications. All individually QA checked and metrology tested for quality to ensure parts meet customer specification. Supplied in a range of sizes and shapes with custom coatings tailored to meet your individual applications. Knight Optical supply precision optical components to customers within Photographic Applications. Our Circular Polarisers consist of a quarter wave plate cemented to a linear polariser. While a linear polariser may be used to reduce glare during photography (such as reflection from the surface of a body of water), autofocus systems struggle to correctly focus on linearly polarised light. With the addition of the quarter wave plate, this has little impact on the intensity of incident light to the sensor, but it makes autofocussing much easier. For more information read PDF…

CMOS sensors are used within commercial grade Digital SLR cameras as a replacement for the more expensive CCD. These CMOS sensors are extremely sensitive to IR light, which can lead to discolouration. IR cut filters are used to block the IR light, meaning that photographs are taken with life-like colours. Colour Glass Filters can be used in variations of Bandpass, Long pass and Short pass, depending on which wavelengths of light need to be blocked resulting in different key areas being more easily distinguished. Knight Optical offers Colour Glass and IR cut filters for such an application, with a wide range of band widths and cut on/off wavelengths. As above these are available as Bandpass, Long pass or Short pass filters and we can also offer customised filters with coatings specific to the wavelength of your choice. We hold a massive inventory of IR cut, Bandpass, Long Pass and Short Pass filters: Read PDF for more info….

Knight Optical We offer Stock Polarisers used in the visible range in cameras/photography. We supply a range of Polarizer options for a range of applications. All individually QA checked and metrology tested for quality to ensure parts meet customer specification. Supplied in a range of sizes and shapes with custom coatings tailored to meet your individual applications. Linear Polarisation can be split into P-Polarised (Light where the electric field is Parallel to the plane of incidence) and S-Polarised (Light where the electric field is Perpendicular to the plane of incidence) light, where a polariser can be used to eliminate one plane of polarisation. This is done to decrease ‘glare’ (reflections on the surface) when an image is being taken, and increase the contrast. This is used often with cameras to obtain ‘better’ image quality at the expense of an image that appears slightly darker. For more information read the PDF….

We can supply you with a custom made Diamond turned aspheric lenses for use within Thermal Imaging Cameras. Thermal Imaging Cameras work similarly to traditional visible camera systems; while traditional cameras form images using visible light; thermal cameras form images using infrared radiation; operating in wavelengths as long as 14µm. Spherical aberration occurs in common singlet lenses, which results in an image that appears distorted, aspheric lenses correct spherical aberration. An aspheric lens surface is designed non-spherical, which allows a single component lens to collimate or focus highly divergent rays, potentially replacing a multi-lens system. This in turn provides the camera system with a better image quality. Knight Optical offers diamond turned aspherics from a range of infrared materials including Germanium (Ge), Calcium Fluoride (CaF₂), Zinc Sulphide (ZnS), Zinc Selenide (ZnSe), Aluminium (Al) and chalcogenide glasses like AMTIR (Ge33As12Se55 ) PDF FOR INFO

Knight Optical has successfully launched a range of Stock Optical Domes for Submersible ROVs underwater imaging, sensing and exploration applications, where protection of electronic sensor systems from harsh liquid and gas environments is essential.

Knight Optical is a trusted, established and reliable supplier to manufacturers of underwater ROVs for surface and deep water exploration. With our excellent record delivering quality, metrology tested optical domes & windows; we like to think we are your best solution for custom ROV dome and window solutions. Our products are used by satisfied customers in the ROV industry worldwide. Contact our experts and find out why! For more information read PDF

Our precision grade N-BK7 windows are often used to seal optical enclosures & act as a protective window for the optical and electrical component behind the window, particularly within CCTV and ANPR systems where there is a risk of damage. N-BK7 provides excellent transmission in the visible and near infrared spectrum which can be enhanced still with our Anti Reflective coatings. Our stock range of ¼ wave N-BK7 or equivalent windows are supplied either uncoated or with the option of an Anti-Reflective coating on both faces with extended BBAR for visible and NIR applications within the 450-900nm wavelength range. We can also offer custom solutions for your application, whether it is a custom size or a coating to optimise a different wavelength range, beamsplitter coated or mirror coated to meet your bespoke requirements.

Knight Optical offer a range of Stock Achromatic Doublet Lenses for use within Holography. Holography can be said to be a photographic recording of a light field, like an audio recording. This recording is typically 3 dimensional and does not require the use of any special equipment e.g. glasses or headset to view. These images are produced using laser light which are passed through a recording medium which “records” the depth an arrangement of the final image. Achromatic Doublets are used in holographic systems & correct for chromatic aberrations which exist in singlet lenses. This is when different wavelengths of light refract at different rates. The doublet lens helps to correct this by facilitating the focusing of the light to the same point. In holographic systems the aim is to form an image which is as close to real life as possible. Therefore, it is critical for the image to be as clear as possible and free from distortions and aberrations. Read PDF for more info
