Beam splitter prism
PRODUCT CATEGORIES
- The beam splitting prism is coated with a layer of film on the inclined plane of the right angle prism, and then glued with the same right angle prism to form a cubic splitting prism. The astigmatism of the flat plate spectroscope can be avoided, the coating is not directly exposed, and it is not easy to be damaged and corroded.
- Compared with the flat plate spectroscope, the reflected and transmitted light paths of the spectroprism are equal. When transmitting light, the beam splitting prism has no influence caused by light deviation, so there will be no problems of beam translation, ghost image and interference. Used for spectroscopic and imaging. Long time calibration is not required for 45 ° incidence.
