SLB-80B-200PIR2 80.0 mm Dia. x 201.8 mm FL; Coated; Double-Convex Lens 750-1550nm

The SLB-80B-200PIR2 is a high-quality lens from OptoSigma, designed for use in the 750-1550nm wavelength range. This lens is a spherical lens with a base shape of a circle, featuring a double-convex design. The lens has a diameter of 80.0 mm and a focal length of 201.8 mm, providing a high level of magnification and precision.

The lens is made from n-bk7 schott, a material known for its excellent optical properties. This material ensures that the lens provides clear, distortion-free images, making it ideal for use in a wide range of applications. The lens also features a coating on both the front and back surfaces, further enhancing its performance. The coating, opt ir2, is specifically designed to optimize the lens's performance in the infrared spectrum.

The geometry of the lens is carefully designed to provide optimal performance. The thickness at the edge of the lens is 3.0 mm, while the thickness at the center is 10.8 mm. The lens's effective focal length (EFL) is 201.8 mm, and the radius of curvature of the first surface (R1) is 207.6 mm, while the radius of curvature of the second surface (R2) is -207.6 mm. The back focal length (BFL) of the lens is 198.2 mm.
