68-806 20 mm Dia. Potassium Bromide Protective Flat Window; t=2 mm Uncoated

The 68-806 is a 20 mm diameter, 2 mm thick uncoated Potassium Bromide (KBr) protective flat window, sourced from the reputable vendor, Edmund Optics. This window is a type of optical element, specifically designed for use as a protective barrier in optical systems.

The window's base shape is circular, making it suitable for a wide range of applications where a circular aperture is required. The geometry of the window includes a diameter of 20 mm and a thickness of 2 mm, providing a robust yet compact design.

The material of the window is Potassium Bromide, identified by the Material ID "uvfs mal- 1965". This material is often used in optical systems due to its transparency in the visible light spectrum, with a wavelength of 587.6 nm. The window's shape is that of a thin lens, further enhancing its optical properties.

Notably, this window is uncoated, meaning it does not have any additional layers applied to its surface. While coatings can enhance the performance of optical elements, an uncoated window can be advantageous in certain applications where simplicity, cost-effectiveness, or specific optical properties are desired.

The window's current status is "in stock", according to the vendor's website, ensuring quick and reliable availability for your optical system needs.
