63-217 127.0 x 177.8 mm Float Glass High Efficiency Protective Flat Window; t=1 mm BBAR 425-700nm

This product is a high-efficiency window offered by Edmund Optics, a renowned vendor in the optical industry. The window, identified with the name 63-217, is a flat, rectangular component designed to protect optical surfaces while maintaining high transmittance across the visible spectrum.

The window measures 127.0 mm in width and 177.8 mm in length, making it suitable for various applications that require a larger optical aperture. It has a thickness of 1 mm, providing a good balance between mechanical strength and light weight. The window is made of soda lime glass, a common material in the industry due to its excellent optical properties and availability.

The window features a broadband anti-reflection (BBAR) coating on both the front and back surfaces. This coating is designed to minimize reflection losses across the 425-700 nm wavelength range, a region that covers the entire visible spectrum. As a result, the window ensures high transmittance, enhancing the performance of the overall optical system.

The window is classified as a thin lens, indicating that its thickness is significantly smaller than its other dimensions. This characteristic, combined with its rectangular shape, makes it an ideal choice for applications that require a flat, transparent barrier with minimal optical power.
