37-703 40 mm Dia. AR Coated Sapphire Protective Flat Window; t=2 mm VIS-NIR 400-1000nm

This product is a 40 mm diameter Flat Window, sourced from the reputable optical components vendor, Edmund Optics. The window is made of Sapphire, a material with the chemical formula Al2O3, and has a thickness of 2 mm. Sapphire is known for its exceptional hardness, second only to diamond, making it highly resistant to scratches and abrasions.

The window features an Anti-Reflective (AR) coating, specifically the edm visnir0sp2002000 coating, on both the front and back surfaces. This coating is designed to minimize reflection and optimize transmission in the Visible (VIS) and Near-Infrared (NIR) regions of the spectrum, from 400 to 1000 nm. This makes the window ideal for applications that require high transmission and low reflection, such as in imaging systems, spectroscopy, and beam delivery systems.

The window is shaped as a Thin Lens, which can have implications for its optical performance depending on the specific application. It is essential to consider the lens's curvature and the material's refractive index when incorporating this window into an optical system.

The window is currently in stock and available for purchase through the Edmund Optics website, as indicated by the weblink status. For more detailed information, users are encouraged to visit the provided weblink.
