SLB-80B-200PIR1 80.0 mm Dia. x 201.8 mm FL; Coated; Double-Convex Lens 633-1064nm

The SLB-80B-200PIR1 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 80.0 mm and a focal length of 201.8 mm, making it suitable for a wide range of optical applications.

The lens is made from n-bk7 schott, a popular optical glass due to its excellent optical properties and relatively low cost. The geometry of the lens includes a thickness edge of 3 mm and a thickness center of 10.8 mm. The effective focal length (EFL) is 201.8 mm, while the back focal length (BFL) is 198.2 mm. The radii of curvature for the first and second surfaces are 207.6 mm and -207.6 mm, respectively.

The SLB-80B-200PIR1 comes with a coating on both the front and back surfaces. This coating, identified as opt ir1, is specifically designed to enhance the lens' performance in the infrared region of the spectrum. The lens is currently in stock and available for immediate purchase, as indicated by its valid weblink status.
