68-814 20 mm Dia. Sodium Chloride Protective Flat Window; t=2 mm Uncoated

The 68-814 is a 20 mm diameter Sodium Chloride Protective Flat Window, with a thickness of 2 mm and no coating. This window is sourced from Edmund Optics, a reputable vendor in the optical industry.

This optical component is classified as a Window, specifically a Flat Window, due to its planar geometry. The base shape is circular, making it suitable for applications requiring a circular aperture. The window has a diameter of 20 mm and a thickness of 2 mm, providing a balance between optical performance and structural integrity.

The material of this window is identified as "uvfs mal- 1965", a unique identifier that may correspond to a specific grade or treatment of Sodium Chloride. The wavelength of 587.6 nm suggests that this window is designed for use in the visible spectrum.

The window's shape is described as a Thin Lens, indicating that it has minimal optical power and is primarily used for protection or isolation of optical surfaces. The absence of a coating means that the window's surface properties are determined by the base material.
