39-262 6.35 mm Dia. AR Coated Sapphire Protective Flat Window; t=0.5 mm NIR II 750-1550nm

The 39-262 is a high-quality protective flat window, boasting a diameter of 6.35 mm and a thickness of 0.5 mm. This window is made from sapphire, a material with the chemical formula al2o3, and is sourced from the reputable vendor, Edmund Optics.

The window is designed for use in the near-infrared (NIR) II region, specifically for wavelengths between 750nm and 1550nm. This makes it ideal for a wide range of applications that require precise optical performance in this spectral range.

The 39-262 is coated with the EDM NIR-II standard curve on both the front and back surfaces. This anti-reflection (AR) coating is specifically designed to reduce reflection and increase transmission in the NIR II region. The coating ensures optimal performance and minimal loss of light, making it a reliable choice for demanding optical applications.

The window is shaped as a thin lens, which is a type of lens with a short focal length and a small amount of optical power. This shape is often used in compact optical systems where space is at a premium.

According to the vendor's website, the 39-262 is currently in stock, making it a readily available option for those in need of a high-performance NIR II window.
