Narrow bandpass filter allow small light through, the narrower ,the more pure of the light.Sunday is producing standars narrow bandpass filter Read more...

Fluorescence imaging utilises different optical filters to excite a fluorescent dye or protein and direct the resulting emitted wavelengths to the detector.

At Knight Optical, we are pleased to announce our new range of fluorescence filter sets. Each set comprises of an excitation bandpass filter, an emission bandpass filter, and a dichroic beamsplitter, that have been carefully d... Read more...

This ND filters provides linearly varying attenuation or beamsplitting in the visible and near infrared region.

The optical density varies linearly across the length.Attenuation is achieved by a thin film of Ni-Cr-Fe protected with an overcoat of SiO. The rear surface is broadband AR coated for the visible region. Read more...
