SLB-60B-170PIR2 60.0 mm Dia. x 171.4 mm FL; Coated; Double-Convex Lens 750-1550nm
The SLB-60B-170PIR2 is a high-quality lens from OptoSigma, designed for use in the 750-1550nm wavelength range. This lens is a spherical, biconvex design, featuring a diameter of 60.0 mm and a focal length of 171.4 mm. The lens is made from n-bk7 Schott glass, a popular material due to its excellent optical properties and versatility.
The lens has a center thickness of 8.1 mm and an edge thickness of 3 mm, providing a robust and durable structure. The front and back surfaces of the lens are coated with Opt IR2, a broadband anti-reflection coating that enhances transmission and reduces surface reflections. This coating is specifically designed for the 750-1550nm wavelength range, ensuring optimal performance in infrared applications.
The lens's geometry is defined by its radii of curvature, with r1 at 176.46 mm and r2 at -176.46 mm. These radii contribute to the lens's double-convex shape, which is known for its ability to focus light efficiently. The back focal length of the lens is 168.7 mm, and it has no inner or outer radius, indicating a uniform curvature throughout.
