Optical imaging

New craft 6: Environmentally friendly electroless nickel plating. Nickel plating in strict accordance with customer requirements,we can control the accurate thickness.

When it comes to a high quality IR Cut filter, it is the substrate with the coating applied that affects the performance. Knight Optical provide high quality wafers for precisely this, and the surface quality of our substrates eliminates blotching at the sensor which occurs on lower quality substrates especially where IR Cut filters are concerned. Our wafers are produced as thin as 500μm & provide exceptional surface quality. However, we can manufacture to a fully customised specification with a wafer thickness as little as 10 μm. Our substrates for stock or custom can be manufactured from a great deal of materials including: •Quartz •Borosilicate •BK7 or equivalent •Sapphire •And many more. Depending on your application for the IR Cut Filter, we can help advise on the best achievable optic for your application. Please read PDF for full specification

We carry out applied research in our own test field and laboratory in order to constantly further develop our products, but also so as to be able to present our customers with innovative new developments. Furthermore, we regularly participate in cooperative projects of the Federal PhysicalTechnical Institute (PTB PhysikalischTechnische Bundesanstalt) with the economy. We also maintain close cooperative links with the universities of DuisburgEssen and Karlsruhe. We would also like to support you in research with our products. Please contact us.

Knight Optical can offer Custom Homogenizing Rods for use within Fluorescence Imaging. Knight Optical supply precision optical components to customers in the medical industry for applications such as fluorescence illumination, microscopy and imaging. Homogenizing Rods are used within the application of surgical procedures; within systems designed to help identify which tissues have been exposed to the fluorescent indicator. The Light source will enter a light pipe at a variety of incident angles, which is designed to utilise its total internal reflection to channel the light from the entrance of the light pipe to the exit. The material’s refractive index is the only factor which affects the light pipes critical angle; this defines the angle of acceptance which the total internal reflection will occur at. With this it helps to control the light source being used in medical systems. Read PDF for more info
