Details

A cube beam splitter is formed by coating a film on the inclined surface of a right angled prism and then bonding the same right angled prism together.
It can avoid the astigmatism of the flat beam splitter, and the coating is not directly exposed, making it less prone to damage and corrosion. Compared with a flat beam splitter, the reflection and transmission optical paths of a beam splitter are equal. When transmitting light, the beam splitter prism does not have the impact of light deviation, so there is no problem of beam translation, ghosting, or interference. Used for spectroscopy and imaging. No need for long-term calibration when incident at a 45 ° angle. One of the right angled prisms has a dielectric splitting film layer on top, which has a certain polarization effect, so the emitted light is in a partially polarized state, suitable for energy splitting applications that are insensitive to polarization states.
Guangtan Intelligent not only provides a large number of spot standard spectral prisms, but also can customize spectral prisms according to your needs.
Note: The cubic beam splitter is only suitable for non polarized light splitting. When splitting light beams with certain polarization states (partially polarized light, linearly polarized light, circularly polarized light, elliptically polarized light), please use a depolarizing beam splitter.
