日本SIGMA西格玛光机非偏光立方体半反射镜NPCH-10-6700

日本SIGMA西格玛光机非偏光立方体半反射镜NPCH-10-6700  日本SIGMA西格玛光机非偏光立方体半反射镜NPCH-10-6700 Details ◦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. More Information Catalog Code W3012 RoHS Yes CE No Download Product's Datasheet PDF 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.
