Knight Optical supply stock and custom deviation penta prisms that cover the visual and NIR range. Deviation prisms are an optical component that will redirect a light beam into another known angle relative to the incoming beam. The penta-prism is a deviation prism which is used in cameras with a movable mirror that bends the beam vertical onto the focus graticule. The penta-prism provides a 90° deviation of the beam from the focus plane and, via an eyepiece, the user can aim the camera along the same axis as the beam that is focused onto the detector, electronic or wet film. Deviations through other angles can be accomplished using, for example, abbe constant deviation, littrow, and wadsworth prisms.

Knight Optical can offer UV Fused Silica Lenses for Colour Measurement Applications. Similarly to N-BK7, UV Fused Silica has a fairly consistent transmission across UV/VIS/NIR, meaning that that transmission in each region is almost equal. This in turn means that any image or measurement taken is not skewed towards one colour, and a more accurate measurement can be taken. This can be used in conjunction with an IR Cut Filter in cameras to remove a lot of the NIR noise giving a clearer image with better colour clarity/contrast. UV FS is comparable to N-BK7 or other similar optical glasses in its performance, having a very similar average transmission over the VIS range up to approximately 2000nm and a slightly lower refractive index. The Abbe constants of UV FS are also very similar to that of N-BK7, although slightly higher.

Knight Optical can supply you with a custom made Diamond turned aspheric lenses for use within Thermal Imaging Cameras. We supply a range of diamond turned aspherics 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. 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, Read PDF for more information… 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)

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. They are also available to custom specifications with our capabilities for the two types: •General Dimensions: 5mm to 300mm+ •Angular tolerance: <3arcseconds •Surface form: <1/10th wave @ 633nm •Surface quality: 10:5 •Coating options: AR or Mirror Read PDF for Info

Knight Optical offers a range of precision optical components for use in IPL (Intense Pulsed Light) applications. The most common usage of IPL systems are typically used as photo epilators.Custom Ceramic Reflectors are a key component for this application. The xenon flash lamp which are typically used emit light in 360 degrees. However utilising ceramic reflectors which are light reflectors with a U channel means that light which would normally be wasted i.e. shining backwards is now refocused down into the filters and light guides. Knight Optical provides ceramic reflectors which are typically moulded from alumina. This choice of material is down to its ability to withstand thermal stresses and high reflectivity values.

Ball Lenses are widely used for focusing & coupling light into & out of fibres. With the high refractive index of Sapphire (Al2O3) material, it yields a low spherical aberration that can be used in the range of UV from 200nm up to 5µm, and with it being one of the hardest materials they are resistant to damage. The key feature of ball lenses is their short back focal length allowing for precision coupling where size or space is a limiting factor in the system. Typically used in pairs, where one lens acts as collimator for the second to focus the light back into the coupled fibre. Ball Lenses are manufactured from a single substrate of glad and therefore, depending on the geometry of the input source, can focus or collimate light. Half Ball Lenses can also be used as an interchange with a full ball lens for more compact designs. Read the PDF for more information...

Sapphire (Al2O3) is one of the hardest minerals and optical materials available for use in the range from UV up to 5µm. Sapphire is birefringent and if its use is for critical optical application then the crystal might have to be cut along the zero degree plane, or C-Cut. Random cut is usually cut along a plane that is 60° off-axis as the growth in this direction is the easiest to grow. Random cut is anything that is not the C-Cut angle. Sapphire can fluoresce depending upon the concentration of other minerals within the lattice, for example Iron (Fe) or Chromium (Cr). Clear Sapphire might fluoresce orange when illuminated by UV light if impurities are in the crystal. Fluorescent free Sapphire has to be grown from 'pure' feedstock and seed and in an environment that cannot place impurities into the lattice. Click PDF link to read more …...

Knight Optical can offer UV Fused Silica Windows for Vacuum Applications. UV Fused Silica is a relatively hard optical glass with a very low coefficient of thermal expansion. This means that it is a good choice for us in Vacuum applications, as any difference in temperature will not affect the optical performance. In addition to the above, UV FS has high transmission from UV to NIR meaning that there is little loss of image when it is used for a Vacuum Window/viewport and therefore the quality of the optical system is not compromised. All our UV Fused Silica Lenses are fully inspected on their quality in our ISO 9001 certified, state-of-the-art Metrology laboratory, using our Trioptics Optispheric, and Starrett AV300 and Zygo Verifire XPZ.
