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. Read PDF for more info

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

These dispersing equilateral dispersing prisms have a very simple triangular cross section. Equilateral dispersion prisms are commonly used for wavelength separations, i.e. refracting white light into a rainbow pattern effect. Depending on the material used equilateral dispersion prisms can be used over a wide range of wavelengths. We offer UV Fused silica prisms for use in the ultra-violet wavelength from 170nm and other high index materials which are used for visible applications. Antireflective coatings are applied to most of our high index grade of equilateral dispersion prisms as high index material is sceptical to staining and corrosion which anti-reflective coatings eliminate. Antireflective coatings also help to improve output of the light as they prevent light loss due to surface reflection. The exit beam is in general at an angle to the input beam, this angle depending on the prism material, the wavelength and the incidence angle READ PDF FOR MORE INFO

Mini prisms RSMP10 and RSMP12 plastic housing with spike and prisms in 12.7 and 17.5 mm With the mini prisms RSMP10 and RSMP12, surveyors can now easily take measurements in cracks, gaps and corners. Fixed dimensions (see product drawings) give the surveyor the exact path from the point of measurement to the base of the housing or the tip of the spike. In forensics the prisms are use for the exact surveying of bullet holes. NOTE: For precise measurements, the prism must be directly aligned with the surveying instrument! When using the mini prisms for surveying settlement, the spikes can be removed and thus be inserted or glued into the smallest cracks or gaps. On façades, historical buildings, supports and many other objects, monitoring is possible with measuring points that are barely identifiable for the general public. On concrete or masonry objects, small holes can be drilled to countersink the prisms flush with the surface. RSMP10 with 12.7 mm miniprism: Offset: -10.12 (min
