SLB-80B-300PIR2 80.0 mm Dia. x 301.3 mm FL; Coated; Double-Convex Lens 750-1550nm
The SLB-80B-300PIR2 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 301.3 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 high transmittance and low dispersion, making it ideal for 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 8.2 mm. The back focal length is 298.7 mm, and the radii of curvature for the first and second surfaces are 311.4 mm and -311.4 mm, respectively. The lens does not have an inner or outer radius.
