Half mirrors have an even 1:1 ratio of reflection and transmission in both linear polarized light and normal light source.

◦The reflection to transmission ratio is 1:1 regardless of the polarization condition from the input beam.
◦Depending on polarization, the reflection to transmission ratio of these products does not vary.
◦The laser lines listed correspond to various laser wavelengths.
◦Narrowband multi-layer AR coatings are applied to the four surfaces of the cube.
◦These cubes afe designed for a single wavelength because the effective bandwidth of a non-polarizing coating is narrow.

▶Please contact our Sales Division for customized products. (Customized on size, wavelength or R:T, etc.)
W3802
▶Non-polarizing beam splitter (plate type) is also possible.
▶For a guarantee in reflected wavefront error or transmitted wavefront error, please contact our Sales Division.

Attention

▶Input beam from the prism side is indicated by a “○”.
▶Phase retardation of light input will not be preserved. Use a waveplate for phase compensation.
▶Wavelength dispersion of transmitted and reflected light is derived from refractive index and glass thickness and when diverging or introducing a focusing beam, chromatic aberration or spherical aberration may occur.
