37-704 50.8 mm Dia. AR Coated Sapphire Protective Flat Window; t=3.15 mm VIS-NIR 400-1000nm

This product is a high-quality optical window offered by Edmund Optics, a leading vendor in the field. The window, identified as 37-704, is designed with a diameter of 50.8 mm and a thickness of 3.15 mm, making it a robust and durable option for various applications.

The window is made of sapphire, a material with the chemical formula Al2O3, which is known for its exceptional hardness, second only to diamond. This property makes sapphire highly resistant to scratches and abrasions, ensuring the window's longevity and clarity.

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 reduce reflection and increase transmission in the Visible to Near-Infrared (VIS-NIR) spectrum, specifically between 400 and 1000 nm. This feature is particularly beneficial in applications where maximum light transmission is required, such as in imaging systems, spectroscopy, and optical metrology.

The window's geometry is that of a thin lens, which can be advantageous in certain applications where minimal optical path length deviation is required. The window is currently in stock and available for immediate purchase through the provided weblink.
