SLB-60B-200PIR2 60.0 mm Dia. x 201.2 mm FL; Coated; Double-Convex Lens 750-1550nm
The SLB-60B-200PIR2 is a high-quality spherical lens offered by OptoSigma, designed for use within the wavelength range of 750-1550nm. This lens boasts a base shape of a circle and is constructed from n-bk7 schott material, a popular choice for its excellent optical properties.
The lens features a double-convex geometry, with radii of curvature of 207.6mm for the first surface and -207.6mm for the second surface. This particular lens has a diameter of 60.0mm and a thickness at the edge of 3.0mm, while the thickness at the center measures 7.4mm. The effective focal length (EFL) is 201.2mm, and the back focal length (BFL) is 198.8mm.
The SLB-60B-200PIR2 comes with a broadband anti-reflection coating, Opt IR2, on both the front and back surfaces. This coating enhances the lens' performance by minimizing surface reflections and increasing transmission within the specified wavelength range.
