Neutral Density Filters
Neutral density filters are designed to reduce transmission evenly across a portion of the spectrum.
Colour Glass Bandpass Filters
Colour glass bandpass filters provide a convenient means of limiting the short wave transmittance of a system. We offer a variety of colour glasses covering the visible and near infrared wavelength regions.
Heat Control Filters
The hot and cold mirrors are filters that remove unwanted parts of the spectrum. They may be used for rejecting IR or UV and permitting only the visible part of the spectrum to pass.
Interference Bandpass Filters
Interference bandpass filters are based on the Fabry-Perot effect. Stacks of highly reflective films provide selective interference to reinforce the transmittance at the wavelength of interest and cancel at other wavelengths.
Beamsplitters / Combiners
Cube beamsplitters provide easy alignment and form no ghost images. These beamsplitters come with either metal or dielectric coatings and are available in polarizing and non-polarizing varieties. Different coating types and specifications are available upon request.
Plate beamsplitters have low absorption and beam deviation. Dichroic plate beamsplitters can also be used in reverse as colour combiners, in the red, green, and blue spectrum. These beamsplitters come with either metal or dielectric coatings.
Here you can find specifications for various types of beamsplitters, both single-mode or multi-more:
