NPCH-15-3550 Half Mirror

Product Description

[Features]
· Half mirror capable of obtaining a branching ratio of exactly 1:1 for reflection and transmission even for light sources such as lasers and linearly polarized lights.
· Since dielectric multilayer film and transparent adhesive are used for the reflecting surface and anti-reflective coating is used on the incident/exiting surface, there is less loss of light and the incident light can be used efficiently.
· Even if the polarization direction of linearly polarized light changes, the branching ratio of reflection and transmission (1:1) does not change.
· A lineup that supports lasers of various wavelengths is available.
· Cube type, so if the beam is input vertically, the optical axis of the output light will not move in parallel.
· Also, even if a beam that is the same size as the effective diameter is incident, the transmitted light and reflected light will not be lost or reduced.
· * Irradiate from the prism side marked with a ○.
· * If light enters from the prism of the opposite side, reflectance, branching ratio, and polarization characteristics may vary.
· * Phase differences of incident light are not preserved in reflected light and transmitted light.
· * Use a wave plate for phase difference compensation.
· * Due to the impact of the refractive index of the material and thickness of the glass, wavelength dispersion occurs for transmitted light and reflected light.
· * Also, chromatic aberration and spherical aberration may occur when convergent beam or divergent beam is incident.
