Optical Filters

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 Read more...

CeNing Optics provide a variety of colored glass filters covering the UV, visible and near-infrared wavelength regions. These filters serve as bandpass, broadband, or long-wave pass filters. Read more...

Gas Detection Systems use Interference Bandpass Filters to identify the emission of a type of gas. Different gases emit at a specific wavelength which makes it identifiable when using a relevant Interference Bandpass Filter. These wavelengths are: Read more...

Custom and OEM Optical Filter Development Challenging custom optical filters without prohibitive pricing Read more...

Alluxa's ULTRA Series thin-film optical filters and coatings are specifically designed to be integrated into the most sophisticated instruments used in biotechnology, remote sensing, telecommunications, chemical engineering, robotics, and a variety of other fields. Read more...

Abrisa Technologies carries a large inventory of cost-effective solid colored glass for aesthetic use in the lighting and entertainment, architectural, and landscaping applications. The soda lime glass can be heat strengthened “tempered” for additional thermal shock resistance. Read more...

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. Read more...

Colour Glass filters are useful for selective wavelength absorption and therefore achieve high out of band blocking. Colour glass type Longpass filters have very low transmission in short wavelengths and high transmission in the long wavelengths. Read more...

We may think that Thin Film Deposition is a 20th century technology, but its roots extend much further into the past. Used for coating architectural glass to manipulating light and heat transmission, to the design of absorber layers for solar cells to magnetic thin films for electronic data storage - learn more Read more...

A broad variety of gas transmission cells are available for the analysis of gas and vapour phase components in infrared optical spectroscopy.

These range from short path length gas cells for percent level concentration measurement, to long path length gas cells for part-per-billion concentrations. Options include fixed and variable path length gas cells, as well as ambient Read more...
