47-940 10 mm Dia. Silicon Protective Flat Window; t=1.5mm BBAR 3-5µm
The 47-940 is a circular flat window, measuring 10 mm in diameter and 1.5 mm in thickness, making it a highly portable and compact optical component. This window is constructed from silicon, specifically silicon sal vil 1957, a material known for its durability and resistance to harsh environments.
This window features a broadband anti-reflection (BBAR) coating on both the front and back surfaces. The BBAR coating is designed to reduce surface reflections and increase transmission across a wide spectral range, specifically from 3 to 5 µm. This coating enhances the window's performance in infrared (IR) applications, making it an ideal choice for systems operating in this region of the spectrum.
The window's thin lens shape further contributes to its functionality. This shape allows for easy integration into various optical systems, while also minimizing optical aberrations and distortions.
The window is available from Edmund Optics, a reputable vendor known for its high-quality optical components. According to the vendor's website, the window is currently in stock, ensuring quick delivery times for your optical system needs.
