This is a 15mm diameter, 50mm focal length double-convex lens, offered by the renowned optical vendor, Edmund Optics. The lens is made from the high-quality material n-BK7 Schott, a borosilicate crown glass known for its excellent optical properties.
The lens features a YAG-BBAR coating on both the front and back surfaces, which stands for Yttrium Aluminum Garnet - Broadband Anti-Reflection. This coating is designed to operate within the wavelength range of 500-1100nm, providing superior anti-reflection performance. It significantly reduces surface reflections, thereby enhancing transmission and improving overall system performance.
The geometry of the lens includes a thickness of 1.9mm at the edge and 3mm at the center. The front and back radii of curvature are 51.16mm and -51.16mm respectively, with a back focal length of 49mm. The lens is spherical in shape, a common choice for its simplicity and versatility in optical systems.
