SLB-25B-35PIR1 25.0 mm Dia. x 36.1 mm FL; Coated; Double-Convex Lens 633-1064nm
The SLB-25B-35PIR1 is a spherical lens with a base shape of a circle, offering a diameter of 25.0 mm and a thickness at the edge of 2.0 mm. The lens has a thickness at the center of 6.4 mm and an effective focal length (EFL) of 36.1 mm. The radii of curvature for the first and second surfaces are 36.33 mm and -36.33 mm, respectively, while the back focal length (BFL) is 33.9 mm.
This lens is made of n-bk7 schott material, a popular choice for its high refractive index and low dispersion. The lens features a double-convex shape, which is beneficial for applications requiring a high numerical aperture and a short focal length.
The SLB-25B-35PIR1 comes with a coating of opt ir1 on both the front and back surfaces. This coating is specifically designed for the infrared region, enhancing the lens's performance in the 633-1064nm wavelength range. The lens is sourced from OptoSigma, a reputable vendor known for its quality optical components.
