High Power Polarization Beamsplitter
PRODUCT CATEGORIES
INOUIRY
High-power polarizing cubic beam splitter is formed by coating the inclined surface of a right-angle prism with a film and gluing a similar right-angle prism.
Compared with the beam splitter plate, the reflected and transmitted light of the beam splitter are equal in optical path, and there is no problem of beam translation, ghost image and interference. It is used for beam splitting and imaging. No long-term calibration is required when the incident light is at a 45° angle. The P component of the incident light is completely transmitted, while the S component of the incident light is reflected at a vertical 90° direction.
Mainly used to separate S polarization and P polarization
No glue in the optical path
High extinction ratio
High damage threshold
RoHS compliant
