SLB-25B-40PIR2 25.0 mm Dia. x 41.0 mm FL; Coated; Double-Convex Lens 750-1550nm
The SLB-25B-40PIR2 is a high-quality lens from OptoSigma, designed for use in the 750-1550nm 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 stability. The thickness center measures 5.9 mm, providing a balance between compactness and optical performance. The effective focal length (EFL) is 41.0 mm, making it suitable for a wide range of optical systems.
The lens features a double-convex design with radii of curvature R1 at 41.52 mm and R2 at -41.52 mm. This design allows for excellent optical performance and low distortion. The back focal length (BFL) is 39.0 mm, which should be considered when designing the optical system.
The lens is made from n-bk7 schott material, a common and reliable option for optical elements. It comes with a front and back coating of opt ir2, which enhances its performance in the specified wavelength range.
