WKB2500 25 mm Dia. Potassium Bromide Round Window; t=4mm Uncoated

The WKB2500 is a 25 mm diameter Potassium Bromide (KBr) round window, with a thickness of 4mm, sourced from Knight Optical. This uncoated window is a type of flat window, designed in a circular base shape, and features a thin lens geometry.

Potassium Bromide is a common material used in optical applications due to its excellent transmission properties in the infrared region of the spectrum. The WKB2500, in particular, is designed for use with a wavelength of 633 nanometers, making it suitable for a wide range of optical systems and instruments.

The window is uncoated, meaning it does not have any additional layers applied to its surface. This can be beneficial in certain applications where a natural surface is preferred, or where the coating could interfere with the optical properties of the system. However, it's important to note that uncoated surfaces can be more susceptible to environmental factors such as dust, moisture, and scratches.

Knight Optical, the vendor, is a reputable supplier of optical components, ensuring the quality and reliability of the WKB2500. The window is currently in stock and available for immediate purchase, as indicated by the "weblink status" field in the item data.
