83-357 50 mm Dia. Germanium Protective Flat Window; t=1 mm BBAR 8-12µm

The 83-357 is a 50 mm diameter Germanium Flat Window, boasting a thickness of 1 mm and equipped with BBAR (Broadband Anti-Reflection) coating for the 8-12 µm wavelength range. This product is sourced from the reputable optical vendor, Edmund Optics.

This Window is a type of optical component designed to protect other optical elements from environmental factors such as dust, dirt, and moisture, without significantly altering the light passing through. The Flat Window variant is characterized by its planar geometry, ensuring minimal distortion to the incident light.

The Window's base shape is circular, with a diameter of 50 mm, providing a large aperture for efficient light transmission. The thickness of 1 mm offers a balance between mechanical strength and light transmission, minimizing the risk of deformation while maintaining high optical quality.

The Window is made of Germanium, a material with a high refractive index and excellent transparency in the infrared region, making it ideal for applications in the 8-12 µm wavelength range. The BBAR coating on both the front and back surfaces further enhances the Window's performance by reducing reflection and increasing transmission in this wavelength range.

The Window's shape is defined as a Thin Lens, indicating its suitability for use in optical systems where a flat, thin, and highly transparent element is required. The Window's geometry, material, and coating make it a versatile component for various applications, including infrared spectroscopy, thermal imaging, and other infrared-based technologies.
