日本SIGMA西格玛光机非偏光立方体半反射镜NPCH-10-6700

◦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.

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