89-293 50mm Dia. x 250mm FL; YAG-BBAR Coated; Double-Convex Lens YAG-BBAR 500-1100nm
Discover the 89-293 Double-Convex Lens, a high-quality optical component designed and manufactured by Edmund Optics. This lens boasts an impressive 50mm diameter and a focal length of 250mm, making it suitable for a wide range of applications.
The lens is crafted from the renowned N-BK7 Schott glass, a material known for its excellent optical properties and versatility. The base shape is circular, ensuring uniform light distribution and minimal distortion. The geometry of the lens is meticulously designed with a thickness of 2.5mm at the edge and 4.93mm at the center, optimized for superior performance.
The 89-293 lens features a YAG-BBAR coating on both the front and back surfaces, enhancing its optical efficiency within the wavelength range of 500-1100nm. This coating reduces reflection, improves transmission, and increases the overall durability of the lens.
The lens's shape is spherical, with radii of curvature R1 and R2 at 257.57mm and -257.57mm, respectively. These parameters contribute to the lens's exceptional light-bending capabilities and minimal aberration. The back focal length (BFL) is 248.37mm, and the lens has no inner or outer radius, ensuring maximum light transmission.
