Chromium plate half mirrors are plate beamsplitters that are coated with chromium (Cr) on the front surface of optical parallels or wedged substrates. The other surface is coated with multi-layer anti-reflection.
◦Half mirror divides input beam into reflectance and transmittance ratio of 1:1. A beamsplitter of R:T=1:1 is called “Half Mirror”.
◦Approximately one third of the input beam is lost because of the absorption of chromium. However these beamsplitters do not depend on wavelength, polarization and angle of incidence of the input beam, and provide a highly neutral reflectivity.
◦Plate beamsplitters have beam deviations on transmission and ghost on rear surface reflections. Wedged substrates are used to prevent ghosting.
▶Please contact our Sales Division for customized products. (Customized on size, wavelength or R:T, etc.)
▶For a guarantee in reflected wavefront error or transmitted wavefront error, please contact our Sales Division with your requests.
▶Please refer to here for Wavelength Characteristic Data (Reference Data, EXCEL file format).
▶The beam deviation at transmission of a wedged beamsplitter is large compared to a one made of optical parallel.
▶The amount of beam deviation of a beamsplitter depends on the thickness of the substrate, the wavelength or the angle of incidence of the input beam.
▶Transmission curves are based on actual measurements and may vary with manufacturing lots.
▶Surface flatness is the reflected wavefront distortion of the surface prior to coating.
▶Be sure to wear laser safety goggles when checking optical path and adjusting optical axis.
