The wedge angle of the ZnSe infrared broadband wedge beam splitter and the anti-reflection coating on its rear surface effectively suppress ghost image interference caused by back-surface reflection. The high-precision substrate guarantees excellent wavefront accuracy for both reflected and transmitted beams. Zinc Selenide (ZnSe) is a hazardous substance. Please wear gloves during handling to avoid direct skin contact, and wash hands thoroughly after use.
Note: This series is intended for unpolarized light splitting only. For intensity splitting of polarized light (partially polarized, linearly polarized, circularly polarized, elliptically polarized), use depolarizing beam-splitting prisms.
