SLB-60B-80PIR2 60.0 mm Dia. x 82.4 mm FL; Coated; Double-Convex Lens 750-1550nm
OptoSigma presents the SLB-60B-80PIR2, a spherical lens with a base shape of a circle and a double-convex design. This lens boasts a diameter of 60.0 mm and a focal length of 82.4 mm, making it a versatile choice for various optical applications. The lens is made from n-bk7 schott material, a popular choice for its high refractive index and low dispersion.
The SLB-60B-80PIR2 features a coating of opt ir2 on both the front and back surfaces, enhancing its performance in the 750-1550nm wavelength range. This coating is designed to improve transmission and reduce reflection, making it an ideal choice for infrared applications.
The lens has a central thickness of 14.2 mm and an edge thickness of 3 mm, providing excellent structural integrity. The inner and outer radii are 0 mm, indicating a uniform curvature throughout. The back focal length (BFL) is 77.6 mm, a critical factor in determining the lens's overall performance in a system.
