68-809 25 mm Dia. Potassium Bromide Protective Flat Window; t=5 mm Uncoated

The 68-809 is a 25 mm diameter, 5 mm thick uncoated Potassium Bromide (KBr) protective flat window, sourced from the reputable vendor, Edmund Optics. This window is identified by the Material ID [uvfs mal- 1965] and is designed to provide reliable protection for optical systems while minimally affecting the path of light.

The window's base shape is circular, making it suitable for a wide range of applications. The KBr material is known for its excellent transmission properties in the infrared region, with a peak wavelength of 587.6 nm, making this window an ideal choice for applications that require infrared transmission.

The window is uncoated, which means it does not have any additional layers to enhance its optical properties. However, this also means that it is less susceptible to damage from environmental factors, making it a durable choice for protective applications.

The window's geometry, including its diameter and thickness, are designed to provide a balance between strength, weight, and optical performance. The 5 mm thickness provides robustness while minimizing optical distortion.
