SLB-20B-120PIR1 20.0 mm Dia. x 120.5 mm FL; Coated; Double-Convex Lens 633-1064nm
The SLB-20B-120PIR1 is a high-quality spherical lens offered by OptoSigma, designed for use in the 633-1064nm wavelength range. This lens, with a base shape of a circle, is a double-convex lens, meaning it has two convex surfaces.
The lens has a diameter of 20.0 mm and a thickness at the edge of 2.0 mm, while the thickness at the center is 2.8 mm. The effective focal length (EFL) of this lens is 120.5 mm, and the back focal length (BFL) is 119.5 mm. The radii of curvature for the first and second surfaces are 124.56 mm and -124.56 mm, respectively.
The lens is made of n-BK7 Schott, a popular optical glass known for its excellent optical properties. It is coated with Opt IR1 on both the front and back surfaces, which is designed to enhance its performance in the infrared region of the spectrum.
