The ZNSBS10 IR Beamspliter is a 25.4 mm diameter, 3.00 mm thick Zinc Selenide beamsplitter with 50/50 reflection/transmission ratio optimized for45° angle of incidence. This beamsplitter is designed for broadband infrared applications covering spectral range from 7 µm to 14 µm. The back surface of the beamsplitter has a 3 arc minutes wedge to reduce undesired interference effects caused by the back reflections from both surfaces of the optics.
