45-461 20 mm Dia. Borofloat33 Protective Flat Window; t=3.3 mm Uncoated

The 45-461 is a 20 mm diameter, 3.3 mm thick uncoated Borofloat33 protective flat window, sourced from Edmund Optics. This window is a flat, circular optical component designed for use in various applications where protection from environmental factors is required without significant optical power.

Borofloat33 is a low-alkali glass with excellent transparency across the visible spectrum, making it an ideal material for optical windows. It boasts high homogeneity, low auto-fluorescence, and superior chemical resistance. The 3.3 mm thickness of this window provides robust protection while maintaining a relatively lightweight design.

The window's uncoated surface ensures broadband transmission without the risk of coating interference. However, it may be more susceptible to environmental factors such as dirt, dust, or moisture compared to coated alternatives.
