Linear Variable Bandpass Filters for Hyperspectral Imaging (HSI)
Filter wheels with no spaces between the glass segments, motors, encoders and timing marks are available
Custom Filters using filter glass and thin film coatings
We hold a massive inventory of Bandpass, Long Pass, Short Pass, Band-Blocking and Color-Correction filters.
Knight Optical offers a comprehensive range of optics for LiDAR applications
Our long-pass stock range of color glass filters have uniform spectral transmission properties over their entire aperture
Knight Optical offers Color Glass Filters for applications, such ANPR cmaeras, be it either long pass or bandpass filters
Knight Optical is able to supply custom interference band-pass filters for use in the IR (1to 40µm) wavebands
Glass Neutral Density filters attenuate light by absorption just like the gelatin neutral density filters. Glass ND Filters are more robust
When it comes to a high-quality IR Cut filter, it is the substrate with the coating applied that affects performance we provide high quality wafers for precisely this!
