68-819 50 mm Dia. Sodium Chloride Protective Flat Window; t=3 mm Uncoated

The 68-819 is a circular flat window with a diameter of 50 mm and a thickness of 3 mm, sourced from Edmund Optics. This window is made of Sodium Chloride, specifically UVFS MAL-1965, and is uncoated.

As a flat window, it is designed to protect optical surfaces from environmental hazards while minimally affecting the light path. Its thin lens shape ensures a compact design, making it suitable for various applications.

The window is designed to work optimally at a wavelength of 587.6 nm, although it can be used across a broader spectrum. The uncoated surface allows for versatility in use, as it does not introduce any specific coating-related chromatic aberrations or reflectivity characteristics.
