63-648 20mm Dia. x 50mm FL; NIR I Coated; Double-Convex Lens NIR I 600-1050nm
The 63-648 is a high-quality double-convex lens, boasting a 20mm diameter and a focal length of 50mm. This lens is sourced from Edmund Optics, a renowned vendor known for their extensive catalog of optical elements. The lens is designed for use within the near-infrared spectrum, specifically between 600nm and 1050nm, making it ideal for a variety of applications within this range.
The lens is constructed from N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. The double-convex shape of the lens, characterized by two convex surfaces, provides a wide range of focusing capabilities. The lens has a thickness of 1.52mm at the edge and 3.5mm at the center, offering a robust and durable design.
The 63-648 lens features a standard curve coating on both the front and back surfaces. This coating, identified as EDM NIR-I Std Curve, is specifically designed to enhance performance within the near-infrared spectrum. It ensures high transmission rates and reduces unwanted reflections, thereby improving the overall efficiency and quality of the optical system.
