The 36-939 is a circular, thin lens-shaped window, 50 mm in diameter and 1 mm thick, sourced from Edmund Optics. This window is made from UVFS material with the ID 'uvfs mal- 1965', and is coated with a standard UV-VIS coating on both the front and back surfaces, as per the 'edm uv-vis std curve'.
The UVFS material is a type of fused silica, specifically designed for use in the ultraviolet and visible light spectrum, spanning from 250 to 700 nm. This makes the 36-939 an ideal choice for applications that require protection from UV and visible light, while maintaining high transmittance within this spectrum.
The window's thin design and circular shape contribute to its versatility, making it suitable for a wide range of optical systems. The 36-939 is currently in stock and available for immediate purchase through the Edmund Optics website.
