Looking to improve you medical system? Then look no further. Knight Optical presents to you their Dichroic colour filters range. These Dichroic colour filters are typically used in scientific instrumentation or/and medical systems in particular palm vein scanners, ophthalmic diagnostics, professional eye care equipment from optical equipment or ophthalmic instruments. Our Dichroic filters: • Have a hard dielectric coating and are designed to offer high transmission over a specific wavelength while reflecting all other wavelengths. •Offer superior contrast between transmitted and reflected wavelengths. Having a dielectric coating they are perfect for high power applications and do not show the strong fluorescence of certain glass filters. •Are temperature resistant and can be used to reflect heat away from hot lighting systems in addition to their colour correcting properties, unlike traditional polyester type colour filters that melt and distort under thermal conditions.

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. Read PDF for more Information….

Knight Optical We can offer Custom Moulded Aspheric Lenses for use with Laser Diode Collimators. Aspheric lens surfaces are used to correct spherical aberration (where the converging light from a lens does not have a common focal point, resulting in a distorted image) in lasers and imaging. Traditional spherical lenses cannot collimate light effectively because even small angles of incidence can produce spherical aberrations. This can mean that several components may be required to get the desired result. The non-spherical surface of an aspheric lens allows a single component to effectively focus or collimate even highly divergent emissions, potentially replacing a multi-lens system with a single aspheric lens. Therefore Aspheric Lenses that are moulded are ideal for use within laser diode-to-fibre coupling applications. For more information read the PDF.. Typical specs::.

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. READ MORE ...

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.

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.

Knight Optical can offer Custom Homogenizing Rods for use within Electrical Instruments. Electrical instruments use backlight displays to help illuminate and evenly distribute the light source. They can be used as mixers, which is when you want to mix colours from multi-colour LEDs together. The light source will enter a light pipe at a variety of incident angles, which is designed to utilise its total internal reflection to help transmit light from the entrance of the light pipe to the exit. The material’s refractive index is the only factor which affects the light pipe’s critical angle; this defines the angle of acceptance at which the total internal reflection will occur.
