Non-polarizing Cube Half Mirrors NPCH
This is a half mirror that has an even 1:1 ratio of reflection and transmission in both linear polarized light and normal light source. Application Systems ◦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. Optics & ◦The laser line corresponds to various wavelengths. Optical ◦Narrowband multi-layer AR coatings are applied to the four surfaces of the cube. Coatings ◦Because the effective bandwidth of a non-polarizing coat is narrow, these products are designed for a single wavelength.

The variable beam splitter can be used individually. When modifying the incident angle, optics thickness and its refractive Beamsplitters properties, a shift may occur in the light path. To reduce this shift, we highly recommend a light path corrector. Please see Polarizers image below. Lenses ◦Place the variable beamsplitter onto a rotation stage to allow an angle adjustment. ◦Install the light path corrector onto a rotating stage. Multi-Element Optics ◦Position the light path corrector at a similar angle with the variable beamsplitter on an opposite side. ◦If the reflected light of the variable beamsplitter is not used, make sure to place a light cut-off material or a beam Filters diffuser at the edge-end of the light.
