Laser Line Plate Half Mirror 30mm Diameter 157nm
PSMH-30C03-P-157
Laser line plate mirrors are plate beamsplitters that are optically coated with dielectric multi-layer on the front surface of optical parallels or wedged substrates. The rear surface is coated with multi-layer anti-reflection.
◦Half mirrors divide input beam into reflectance and transmittance ratio of 1:1. A beamsplitter of R:T=1:1 is called “Half Mirror”.
◦Any loss from the input beams of this product is minimized because dielectric coatings have no absorption properties. However, the input ratio of reflection to transmission depends on wavelength, polarization and angle of incident of input beam.
◦Plate beamsplitters have beam deviations on transmission and ghost on rear surface reflections. Wedged substrates are used to prevent ghosting.
