Discover Filters & Beamsplitters from Brighten Optics

Filters

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.

Short/Long Wavelength Pass Filters

Short and long wavelength pass filters have a steep transition between the region of transmission and reflection. They have hard, dielectric filter coatings using interference effects rather than absorption to isolate the spectral bands.

Beamsplitters / Combiners

Cube Beamsplitters

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

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.
