45-182 12.5 x 12.5 mm B270 Glass Protective Flat Window with MgF2 Coating

The 45-182 is a 12.5 x 12.5 mm B270 glass protective flat window, designed and manufactured by Edmund Optics. This window is a type of optical element that provides protection to the optical system it is integrated with, while minimally affecting the light path.

The window is made of B270 Schott glass, a borosilicate glass known for its excellent chemical resistance and high transmittance in the visible spectrum. The window's geometry is rectangular, with a width and length of 12.5 mm each, and a thickness of 2 mm. This thickness provides sufficient robustness for the window while maintaining a low profile in the optical system.

The 45-182 window features a magnesium fluoride (MgF2) coating on both the front and back surfaces. This coating is standard for Edmund Optics and is designed to enhance the window's performance in the 400-700 nm wavelength range, which covers the visible spectrum. The MgF2 coating reduces reflection and increases transmission, thereby improving the overall efficiency of the optical system.

The window is designed in the shape of a thin lens, which allows it to be easily integrated into various optical systems. The catalog number for this item is 45-182, and it is currently in stock.
