SLB-40B-40PIR1 40.0 mm Dia. x 42.1 mm FL; Coated; Double-Convex Lens 633-1064nm
The SLB-40B-40PIR1 is a high-quality spherical lens offered by OptoSigma, designed with a double-convex geometry and a 40.0 mm diameter. This lens boasts a focal length of 42.1 mm, making it suitable for a wide range of optical applications.
The lens is made from the renowned n-BK7 material from Schott, a borosilicate glass known for its excellent optical properties. This material ensures high transmission and low dispersion across a wide spectrum, specifically from 633 to 1064 nm.
The SLB-40B-40PIR1 features a coating of opt IR1 on both the front and back surfaces. This anti-reflection coating is optimized for the specified wavelength range, further enhancing the lens's performance by minimizing surface reflections and increasing transmission.
The lens's geometry includes an edge thickness of 2 mm and a center thickness of 12.3 mm, contributing to its robustness and overall optical performance. The back focal length (BFL) is 37.9 mm, and the lens has inner and outer radii of 0 mm, indicating a symmetrical double-convex design.
