SLB-20B-50PIR2 20.0 mm Dia. x 50.7 mm FL; Coated; Double-Convex Lens 750-1550nm

The SLB-20B-50PIR2 is a high-quality lens offered by 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 20.0 mm and a thickness edge of 2.0 mm, ensuring durability and stability. The thickness center measures 3.9 mm, providing a balance between compactness and optical performance. The effective focal length (EFL) is 50.7 mm, making it suitable for medium to long-range optical systems.

The first radius of curvature (R1) is 51.9 mm, while the second radius of curvature (R2) is -51.9 mm, indicating a double-convex lens design. The back focal length (BFL) is 49.3 mm, which is crucial for determining the placement of the lens in an optical system. The lens does not have an inner or outer radius, suggesting a uniform curvature throughout.

The lens is made of 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 is coated with opt ir2 on both the front and back, enhancing its transmission capabilities within the specified wavelength range.
