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.

Aspherics with a range of infrared materials incld Ge, CaF₂, ZnS, ZnSe, & Al - 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 Material::Germanium, ZnSe, Caf2, Silicon, Zinc Selenide (For LWIR) Diameter::Up to 200mm dia +0, -0.02mm Thickness::+/- 0.2mm Flatness::< 1/2 wave over 90% aperture Surface quality::< 40-20 scratch/dig Parallelism::5 arcmin Coating::AR/DLC (3-5 micron, 7-14 micron, 10-12 micron)

IR materials Germanium Calcium Fluoride Zinc Sulphide Zinc Selenide Aluminium - Diamond turning is an Aspherics best friend! Knight Optical can supply you with a custom made Diamond turned aspheric lenses. Diamond turned aspheric optical lenses are typically used in missile guidance systems, night vision/thermal Imaging cameras and other military based optics and commercial infrared systems (IR). The benefit of Diamond Turned Aspheric optics, are that lens shapes can be manufactured very accurately without an expensive tooling cost except for the diamond bit; and is cost efficient for small quantities. Which are ideal for use within the Defence and Aerospace Industry. 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 ).

Stock & custom precision optical filter in materials such as Schott Kopp & CDGM - Knight Optical can offer you Stock and Custom Colour Glass Filters, for use within Inline Cameras in a range of materials of brands such as Schott, Kopp and CDGM. Depending on the achievable wavelength and desired affect you need for the Inline Camera we can find a suitable material for your application. Colour Glass Filters are good for selecting a particular wavelength to be absorbed so that the high out of band blocking in achieved. With regards to the use in Inline Cameras, Colour Glass Short pass Filters are more desirable as they cut out the IR wavelengths mean the imaging is not saturated with the IR giving the image better clarity. Colour Glass Filters are polished sheets of special glass that have been cast with a dye. Colour Glass Filters generally are relatively cheap and very stable. The disadvantage with them is that they are only available in a relatively small number of variants, and so can be restrictive in shortwave selection.  For More Info see PDF...

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.

Knight Optical offer a range of Stock Achromatic Doublet Lenses for use within Light Engines. Light engines are used for applications such as fibre optic lighting displays & in diagnostic tools like western blots & polymerase chain reaction systems. These Light Engines are typically able to produce changing colour displays. Within the light engine are a range of lenses & filters. The lenses help to homogenise and collimate the light, ensuring for a crisp high-quality beam output. Achromatic Doublets are typically used in light engine 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. This is especially important in light engines which typically generate white light.
