Knight Optical are very experienced within the Thermal Imaging market, including anti-reflective and diamond-like-carbon coatings used on the optical components in these systems. Knight Optical know exactly what you are looking for. Thermal imaging uses infrared materials such as Germanium and Silicon, however in there raw form the transmission is not the best it could be. For example, Germanium typically transmits at <45% but with an AR coating applied, it can improve transmission to >60%. This increase in transmission means that the camera sensor receives a better signal through the protective window. Also with protective windows, we can provide high quality DLC coatings. We ensure the coating is Salt Fog Tested to MIL-SPEC standard to ensure that the coating withstands harsh environments. The coating has high mechanical hardness and high resilience to external stress. Read PDF for more information

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

Within medicine the use of polarised light was first introduced back in the70’s; since then it has come leaps and bounds. How it has been used to help with imaging skin pathologies, when the skin is illuminated by linearly polarised light it causes backscattering of the superficial layers of the skin where cancer often arises. This superficial backscattered light can be distinguished from the diffused reflected light when using a detector. Polarised Beam-Splitter Cubes, Sheet Linear Polarisers, and Sheet Circular Polarisers are often used within detection devices for this type of skin pathology imaging. Knight Optical hold a large inventory of Polarisers for use within Skin Cancer Detection devices. •We stock large sheets up to 1270x480mm in some cases; we can cut these into special shapes at short notice. •Mounting options are also available. •Special Glass laminating to CAB polarisers •Special AR coatings.

Optical Sorting Systems are a widely utilized technology used within the food industry; most particularly used in processing harvested foods such as fruits and vegetables, most notably potatoes, and nuts. Optical sorting was designed to help improve product quality, maximize throughput and increase yields. Within an optical sorting system there are four main components, the feed system, the optical system, the image processing software and last the separation system. The optical system utilizes lights and sensors housed above and below the flow of the products being inspected. It works by using a combination of light and sensors to illuminate objects; and to do this Beam-Splitters are one of the optical components used. Within the camera used in the system a Beam-Splitter cube is used to divide the light source coming from a single lens, into different channels; and each channel is filtered to a specific spectral region Read PDF for more data

Binoculars and Periscopes invert an image to make an object appear closer. There are two types of prisms that can be used for binoculars: Porro and Roof Prisms. Porro prisms are used in a pair to create an optical path. The image would pass through the first prism and which then inverts the image, the second prism then flips the image, so it is making the distant object appear closer. Roof prisms work in a similar fashion however are one prism and this design performs in the same way. Used particularly for smaller compact spaces as there are aligned in one piece to its objective lenses. Knight Optical’s Porro and Roof Prisms are available from stock, manufactured from high quality BK-7 or equivalent.

The particle image velocimetry (PIV) is an optical noninvasive working flow velocity measurement method. The flow field is made visible by introducing into the fluid small buoyancy neutral particles – the so called tracers. The particle flow then is illuminated with the aid of a light sheet and recorded at two defined different times within a small time interval with a digital camera. Because the particle move within this time interval with the flow, one can calculate the particles velocity by knowing its path between the two moments of illumination. The result is a velocity vector field of the flow. Here, we assume that the particles are small and follow the flow without any slip. Compared to local methods like LaserDopplerVelocimetry (LDV) with the ParticleImageVelocimetry one can reconstruct a whole flow region An extension of ParticleImageVelocimetry is the combination of PIV with thermometry (PIV/T).

Complex asphere metrology ideally suited for production-level volumes Advances in diamond turning and small-tool deterministic polishing have dramatically increased optical manufacturing capabilities to produce nearly any surface shape. Designers have leveraged these capabilities by increasingly designing aspheric optics into imaging, sensing and laser systems to improve performance and reduce size and weight of optical systems. However, it isn’t just the polishing equipment that is required to produce high quality aspheric optics – metrology is required to guide polishing and material removal from the surface to converge to an ideal surface figure that matches the design closely. A CGH (Computer Generated Hologram) is an optical null element that creates a unique wavefront enabling interferometric testing of complex optical surfaces including freeform, gullwing and off-axis aspheric shapes.
