SLB-25B-25PIR1 25.0 mm Dia. x 26.5 mm FL; Coated; Double-Convex Lens 633-1064nm
The SLB-25B-25PIR1 is a high-quality lens from OptoSigma, designed for use in the 633-1064nm wavelength range. This lens is a Spherical Lens (Convex-Convex) type, featuring a Base Shape of Circular for versatile application.
The lens has a diameter of 25.0 mm and a thickness edge of 2.0 mm, ensuring durability and robustness. The thickness center measures 8.4 mm, providing a balance between weight and optical performance. The effective focal length (EFL) is 26.5 mm, making it suitable for a wide range of optical systems.
The lens's front and back surfaces are coated with opt ir1, providing excellent anti-reflection properties. The first radius of curvature (r1) is 25.95 mm, while the second radius of curvature (r2) is -25.95 mm, indicating a double-convex design. The back focal length (BFL) is 23.5 mm, which is an important parameter for focusing optics.
The lens material is n-bk7 schott, a popular choice for its high refractive index and low dispersion. This lens is currently in stock, as indicated by its weblink status, making it readily available for your optical needs.
