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. Read PDF for full spec

Knight Optical can offer you Plane Mirrors (general, λ/1 and λ/4), for use within 3D Mapping Applications in a range of materials such as Soda-lime float glass, white float glass, and BK7 glass. Plane mirrors also known as front surface mirrors or first surface mirrors are used within 3D Mapping Applications. As stock we hold a number of general purpose, λ/1 and λ/4 with a range of up to 6 types of coatings such as Enhanced Aluminium, Ali/SiO2 and Ali/Mgf2. Our general purpose grade mirrors are made from good quality float glass and generally available in thicknesses of 1mm, 3mm and 6mm as standard. How our mirrors are used within 3D Mapping, is they are used as a sender and receiver of a laser beam that will take a reading of a specific surface, and from that reading it can create a 3D map of the surface that is has read.

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.

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 Toroidal Mirrors for use within Optical Systems. We supply a range of Toroidal Mirrors 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 with Optical Systems. Our Toroidal Mirrors are designed to minimise astigmatism when used in off-axis geometry. They are easier to manufacture than parabolic or ellipsoidal mirrors and therefore can be made much cheap with the same quality. Toroidal mirrors are used for correction of aberration in a range of scientific instrument applications such as spectroscopes monochromators and imaging devices. For more details read PDF…
