49-538 3mm Dia. x -6 FL; NIR I Coated; Plano-Concave Lens 600-1050nm
The 49-538 is a Plano-Concave Lens, a type of spherical lens, with a diameter of 50mm and a focal length of -100mm. This lens is sourced from Edmund Optics, a renowned vendor in the optical industry. The lens is designed for use within the near-infrared (NIR) spectrum, specifically between 600-1050nm, making it suitable for a wide range of applications in this region.
The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. This makes the lens ideal for applications that require high image quality and minimal chromatic aberration. The lens has a thickness of 11.23mm at the edge and 5mm at the center, providing a balanced structure for efficient light transmission.
The 49-538 is coated with Edmund Optics' NIR-I standard curve coating on both the front and back surfaces. This coating enhances the lens's performance in the NIR region by reducing reflection and increasing transmission. The coating is designed to maintain high performance across the entire NIR spectrum, ensuring optimal functionality in your application.
