The 39-419 is a 12.7 mm diameter Zinc Selenide (ZnSe) flat window, boasting a thickness of 1 mm and equipped with Broadband Anti-Reflection (BBAR) coating on both the front and back surfaces. This window is sourced from Edmund Optics, a reputable vendor known for its high-quality optical components.
The window's primary function is to protect optical systems from environmental hazards while minimizing light loss and distortion. The BBAR coating, specifically designed for the 8-12 μm wavelength range, ensures optimal performance in the mid-infrared region. This makes the 39-419 an ideal choice for applications such as thermal imaging, spectroscopy, and other infrared-based technologies.
The ZnSe material is chosen for its excellent optical properties, including high transparency in the infrared region and excellent chemical resistance. The circular geometry of the window, with a diameter of 12.7 mm, is a common shape in optical systems due to its ease of alignment and integration.
The window's thin lens shape further enhances its functionality, allowing for minimal optical aberrations and distortions. This feature is particularly beneficial in high-precision applications where image quality is paramount.
