Optical plate beam-splitter
CVI Melles Griot
Transmission curves are supplied with every component.
Ultrahard, high-damage-threshold coatings are available for all wavelengths from 193 nm to 2100 nm.
Internally reflected ghost images are minimized by an antireflection coating on the rear surface.
Each face is polished to flatness of λ/10 or better.
Beamsplitters are ideal for beam separation or combination.
CVI Melles Griot high energy plate beamsplitters are used to separate a laser beam into two separate beams or to combine beams at right angles to each other. The front surface of the beamsplitter reflects a portion of the incoming beam. The BS1 beamsplitters exhibit almost no absorption and are designed specifically for 45° at the wavelength and polarization being used. Standard substrates have an antireflection coating on the second surface and a wedge of less than five arc minutes. However, the beamsplitter coating can be done on any CVI Melles Griot wedged or plane parallel substrate to meet your application requirements.
