CSM25-20-550 Splitter

[Features]
· A cube type beam splitter in which reflectance and transmittance are divided into 1:2 or 1:3.
· Can be combined with a half-mirror to make 3-branch or 4-branch optical systems with equally distributed light.
· Achieves accurate branching characteristics in a wide wavelength band in white light and visible LED light sources.
· Dielectric multilayer film is used for the coating, so loss of light intensity is minimal, allowing effective light separation.
· 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, spectrum wavelength characteristics may vary.
· * When linearly polarized light such as laser light is used, reflectance and transmittance change depending on the polarization direction.
· * When adjusting branching ratio precisely, ensure the direction of polarization is set to 45 degrees or use circular polarization of light.
· * 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.
