SLB-20B-25PIR1 20.0 mm Dia. x 26.0 mm FL; Coated; Double-Convex Lens 633-1064nm
The SLB-20B-25PIR1 is a high-quality lens from OptoSigma, designed for use in the 633-1064nm 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 20.0 mm and a thickness at the edge of 2.0 mm, while the thickness at the center is 6.0 mm. The effective focal length (EFL) of the lens is 26.0 mm, making it suitable for a variety of optical applications.
The lens is made from n-bk7 schott material, a popular choice for its high refractive index and low dispersion. This material ensures excellent image quality and color correction. The lens features a coating on both the front and back surfaces, specifically an opt ir1 coating. This coating enhances the lens's performance by reducing reflection and increasing transmission, making it more efficient in transmitting light.
The inner and outer radii of the lens are 0, indicating a symmetrical design. The back focal length (BFL) of the lens is 24.0 mm. This lens is currently in stock and available for immediate purchase from the OptoSigma website.
