67-675 50mm Dia. x 150mm FL; NIR II Coated; Double-Convex Lens NIR II 750-1550nm
The 67-675 is a high-quality double-convex lens, designed and manufactured by Edmund Optics, a leading provider of optical components. This lens boasts a 50mm diameter and a focal length of 150mm, making it suitable for a wide range of applications.
The lens is constructed from N-BK7 Schott glass, a popular choice due to its excellent optical properties and versatility. The base shape of the lens is circular, and it features a standard spherical geometry. The radius of curvature for the first surface is 153.49mm, while the second surface has a radius of -153.49mm. The lens has an edge thickness of 4.9mm and a center thickness of 9mm, contributing to its robustness and durability.
The 67-675 lens is coated with Edmund Optics' standard NIR-II coating on both the front and back surfaces. This coating is specifically designed for the near-infrared spectrum, covering the wavelength range of 750-1550nm. It enhances the lens' performance by reducing surface reflections and increasing transmission, thereby improving overall system efficiency.
