39-231 6.35 mm Dia. AR Coated Sapphire Protective Flat Window; t=0.5 mm MgF2 400-700nm

The 39-231 is a high-quality protective flat window offered by Edmund Optics, designed with a diameter of 6.35 mm and a thickness of 0.5 mm. This window is made of sapphire (al2o3), a highly durable and scratch-resistant material, making it an excellent choice for applications requiring a transparent barrier that can withstand harsh conditions.

The window features an Anti-Reflective (AR) coating on both the front and back surfaces, specifically the EDM MgF2 STD CURVE coating. This coating is designed to minimize reflection and optimize transmission in the spectral range of 400-700 nm, which includes the visible light spectrum. The AR coating ensures maximum light transmission, reducing losses due to reflection and improving the overall performance of the optical system.

The 39-231 is available in a thin lens shape, which is beneficial for applications requiring a compact and lightweight optical component. This window is currently in stock and available for immediate purchase through the Edmund Optics website, as indicated by its weblink status.
