39-250 35 mm Dia. AR Coated Sapphire Protective Flat Window; t=1 mm VIS-NIR 400-1000nm
This product is a 35 mm diameter Sapphire Flat Window, offered by Edmund Optics. It is designed for use in the visible to near-infrared spectrum, spanning 400 to 1000 nanometers. The window is 1 mm thick, making it suitable for applications that require a thin, yet robust optical component.
The window is made from Sapphire, also known as Aluminum Oxide (Al2O3), a material renowned for its exceptional hardness and chemical resistance. This makes the window ideal for harsh environments where durability is paramount.
The window features anti-reflective (AR) coatings on both the front and back surfaces. The coating, identified as 'edm visnir0sp2002000', is specifically designed for the visible to near-infrared spectrum, further enhancing the window's performance in its intended range. This coating reduces reflective losses, improving transmission and ensuring optimal performance.
The window is shaped as a thin lens, a design that minimizes optical aberrations and distortions. This makes it suitable for imaging applications where high optical quality is required.
