47-833 5 mm Dia. UVFS Round Protective Flat Window; t=1 mm Uncoated

The 47-833 is a 5 mm diameter, 1 mm thick uncoated flat window made from UVFS (UV Fused Silica) material, sourced from Edmund Optics. This window is designed to protect optical systems from environmental factors while minimally affecting the light path.

The UVFS material, also known as synthetic fused silica, is characterized by its high transparency across a wide spectrum, including the ultraviolet region, making it suitable for applications that require UV transmission. It also exhibits low autofluorescence and a low coefficient of thermal expansion, ensuring dimensional stability over a wide temperature range.

The window's thin lens shape and circular geometry provide a large aperture with minimal obstruction, making it ideal for use in various optical systems. The uncoated surface ensures high damage threshold and low scatter, but it may have higher reflectivity compared to coated surfaces.
