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

Colorimeters measure colour in a substance, for example in water. It defines the measurement of the colour to enable its identification, using the lightwave spectrum. Colorimeters are a form of a spectrophotometer. The use of mirrors in the system, redirect the light beam from the light source to the sample and back to the sensor to enable a reading. Knight Optical provide high quality coated front surface mirrors of varying reflection averages from stock and to custom specifications. Knight Optical provide several metallic coatings such as: •UV Enhanced Aluminium •Enhanced Aluminium •Protected Silver •Protected Gold •Visible Dielectric •NIR Dielectric These are all available as custom coatings depending on your requirements for your colorimeter.
