68-502 30 mm Dia. Zinc Selenide Protective Flat Window; t=3mm BBAR 8-12µm

The 68-502 is a 30 mm diameter Zinc Selenide (ZnSe) protective flat window, with a thickness of 3mm, coated with BBAR (Broadband Anti-Reflection) for the 8-12µm wavelength range. This window is sourced from Edmund Optics, a leading vendor in the optical industry.

The window is designed in a flat format, featuring a circular base shape, making it suitable for a wide range of applications that require broadband anti-reflection coatings. The BBAR coating on both the front and back surfaces of the window ensures minimal reflection and maximizes transmission, making it ideal for infrared (IR) applications.

The ZnSe material is known for its excellent transmission properties in the infrared region, making it a popular choice for IR applications. The window's geometry, with a diameter of 30mm and a thickness of 3mm, provides a robust and durable design, capable of withstanding harsh environments.

The window is classified as a thin lens, indicating its ability to bend light and focus it to a point. This feature can be exploited in various applications, such as imaging systems, beam shaping, and beam splitting.
