Chrome cube half mirror CSCH series

[Features]
· Cube type half mirror that can be used in a wide wavelength range from visible to infrared.
· Can be used for simple experiments, spectroscopic measurements, etc.
· Uses a metal film so that the transmittance has little dependence on wavelength over a wide wavelength range, meaning that the transmittance and reflectance don't change even if the wavelength changes.
· A lineup for visible light and infrared light (for semiconductor lasers) 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.
· * Chromium film has an absorption of approximately 40%, and transmitted light or reflected light can only use approximately 30% of incident light.
· * Irradiate from the prism side marked with a ○.
· * If light enters from the prism of the opposite side, reflectance and reflectance wavelength characteristics will vary due to effects from absorption film.
· * When linearly polarized light such as laser light is used, reflectance and transmittance change depending on the polarization direction.
· * When adjusting the branching ratio to 1:1, 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.
