63-823 9mm Dia. x 13.5mm FL; VIS-NIR Coated; UV Double-Convex Lens VIS-NIR 400-1000nm
The 63-823 is a high-quality spherical lens, boasting a 9mm diameter and a focal length of 13.5mm, sourced from the reputable vendor Edmund Optics. This lens is designed for use within the visible to near-infrared spectrum, spanning 400-1000nm, making it suitable for a wide range of optical applications.
The lens features a double-convex geometry, with radii of curvature of 11.84mm for the first surface and -11.84mm for the second, promoting excellent image quality and light gathering capabilities. The edge thickness measures 1.52mm, while the center thickness is 3.3mm, contributing to the lens' robust construction. The effective focal length (EFL) is 13.5mm, and the back focal length (BFL) is 12.32mm, providing flexibility in optical system design.
The 63-823 lens is crafted from fused silica (mal-1965), a material known for its exceptional transparency and resistance to thermal shock. This makes the lens an ideal choice for applications requiring durability and stability.
The lens is coated with a VIS-NIR coating, denoted as edm visnir0sp2002000, on both the front and back surfaces. This coating is designed to enhance the lens' performance within the visible to near-infrared spectrum, reducing surface reflections and increasing transmission.
