39-410 25.4 mm Dia. Zinc Selenide Protective Flat Window; t=3mm BBAR 3-12µm

This 39-410 Zinc Selenide (ZnSe) Protective Flat Window, offered by Edmund Optics, is a circular window with a diameter of 25.4 mm and a thickness of 3 mm. The window is designed to protect optical components from environmental factors while maintaining high optical quality.

The window is made of ZnSe, a material known for its excellent optical properties, including high transparency in the infrared region. This makes it suitable for applications that operate in the 3-12 µm wavelength range, such as infrared spectroscopy, thermal imaging, and other infrared-based technologies.

The window features a BBAR (Broadband Anti-Reflection) coating on both the front and back surfaces. This coating is designed to reduce reflection and increase transmission across the entire spectral range of the window. The coating specifications are "edm dbbarl znse 312", which refers to a specific type of BBAR coating optimized for ZnSe windows.

The window is shaped as a thin lens, which can be beneficial in certain optical systems where a flat window may introduce unwanted aberrations. The lens shape can help to minimize these aberrations and improve the overall performance of the optical system.
