45-637 12.5 mm Dia. B270 Glass Protective Flat Window; t=2 mm Uncoated

The 45-637 is a circular, flat window with a diameter of 12.5 mm and a thickness of 2 mm. This window is made from B270 glass, a type of borosilicate glass manufactured by Schott. The B270 glass is known for its excellent chemical resistance, making it an ideal choice for protective applications.

This window is uncoated, meaning it does not have any additional layers applied to its surface. This can be beneficial in certain applications where the natural properties of the glass need to be preserved. However, it's important to note that uncoated windows may be more susceptible to environmental factors such as dust, dirt, and moisture.

The window is designed to operate at a wavelength of 587.6 nm, which falls within the visible light spectrum. This makes it suitable for use in applications where visibility is a key factor. The window is also shaped as a thin lens, which can help to minimize distortion and improve the overall optical performance.

The 45-637 window is available from Edmund Optics and is currently in stock. It is part of a larger catalog of optical elements, ensuring that users have a wide range of options to choose from when selecting components for their systems.
