68-804 13 mm Dia. Potassium Bromide Protective Flat Window; t=1 mm Uncoated

The 68-804 is a circular, flat window with a diameter of 13 mm and a thickness of 1 mm, making it a highly portable and compact optical component. Sourced from Edmund Optics, this window is made of Potassium Bromide (KBr), a material with the Mal-1965 Material ID.

Potassium Bromide is a popular choice in optical applications due to its excellent transmission properties, particularly in the infrared region of the spectrum. The window's central wavelength is 587.6 nm, indicating its suitability for applications that require good visibility in the visible light range.

The window is uncoated, meaning it does not have any additional layers to enhance its optical properties or protect it from environmental factors. This makes it ideal for applications where minimal reflection or dispersion is required, and where the environment is controlled to prevent damage to the uncoated surface.

The window is classified as a thin lens, suggesting that it can bend or refract light to some degree. However, without specific curvature details, it's hard to quantify this effect. Nonetheless, this property can be exploited in various optical systems to control or manipulate light.
