11-875 50.8 mm Dia. Calcium Fluoride Protective Flat Window; t=3 mm Uncoated

The 11-875 is a circular, uncoated Calcium Fluoride (CaF2) window with a 50.8 mm diameter and a thickness of 3 mm, sourced from Edmund Optics. This window is designed to protect optical components from environmental factors while minimally affecting the light path.

The window is made of Calcium Fluoride, a popular material in optical applications due to its excellent transparency in the ultraviolet, visible, and near-infrared regions of the spectrum. The window's 3 mm thickness provides robustness while maintaining a low profile in optical systems.

The window is uncoated, meaning it does not have any anti-reflective or other coatings. This can be advantageous in certain applications where a broadband, unaltered transmission is required. However, it may lead to increased reflection at the air-glass interface, which could be mitigated with appropriate coatings if needed.

The window's flat geometry ensures a uniform light path, making it suitable for use in various applications, including imaging systems, beam delivery, and laser applications. The window is currently in stock and available for immediate purchase.
