A window with a substrate made of single-crystal silicon. No absorption in the infrared region up to 6μm. With anti-reflective (AR) coating on the both faces, the product delivers even superior transmission properties highly suitable for windows.
Features
- The AR-coated model offers high transmission properties for a wide range of light (3μm-5μm).
- The product can be used as a window forspecimen observation, laser irradiation, etc.
