39-405 12.7 mm Diameter Zinc Selenide Protective Flat Window with BBAR Coating

The 39-405 12.7 mm Diameter Zinc Selenide (ZnSe) Protective Flat Window is a high-quality optical component designed for a wide range of applications. Sourced from Edmund Optics, this window boasts a 12.7 mm diameter and a thickness of 1 mm, making it a versatile and robust choice for various optical systems.

This window is made from ZnSe, a material known for its excellent optical properties, including high transparency in the infrared region. The ZnSe material is identified as "znse connolly" in the item data, indicating its specific alloy or treatment. The window is designed for use at a wavelength of 10600 nanometers, making it suitable for near-infrared applications.

The window features a Broadband Anti-Reflection (BBAR) coating on both the front and back surfaces. This coating, identified as "edm dbbarl znse 312", is designed to reduce reflection and increase transmission, enhancing the performance of the optical system. The BBAR coating is effective across a broad range of wavelengths, from 3 to 12 micrometers, making this window a versatile choice for many applications.

The window's geometry is defined as a Thin Lens, indicating its potential use in focusing or collimating light. However, its primary function is as a protective window, providing a barrier against environmental hazards while allowing light to pass through.
