This product is a 40 mm diameter Flat Window, offered by the reputable vendor Edmund Optics. The window is made of Sapphire, a material with the Material ID al2o3 mal-1972-n-o, and has a thickness of 2 mm.
The window is designed for use in the Near-Infrared (NIR) region, specifically for wavelengths between 600 and 1050 nm. This makes it suitable for a wide range of applications that operate within this spectral range.
The window features Anti-Reflective (AR) coatings on both the front and back surfaces. The coating on the front surface follows the EDM NIR-I STD curve, while the back surface coating also follows the EDM NIR-I STD curve. These coatings are designed to reduce reflection and increase transmission, thereby enhancing the performance of the optical system in which the window is used.
The window is shaped as a Thin Lens, which is a type of lens where the thickness is much smaller than the diameter. This shape is often used in optical systems where a simple flat window is not sufficient.
The window is currently in stock and available for purchase. For more information, please refer to the vendor's website using the provided weblink.
