SLB-20B-50PIR1 20.0 mm Dia. x 50.7 mm FL; Coated; Double-Convex Lens 633-1064nm

The SLB-20B-50PIR1 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 20.0 mm, with a thickness edge of 2.0 mm and a thickness center of 3.9 mm, providing a robust and durable structure. The effective focal length (EFL) of this lens is 50.7 mm, making it suitable for a wide range of optical applications.

The curvature of the lens is defined by its first and second radii, R1 and R2, which are 51.9 mm and -51.9 mm respectively. These radii contribute to the lens's double-convex geometry, which is designed to minimize spherical aberration and provide superior image quality.

The lens is made from n-bk7 schott material, a popular choice for its high refractive index and low dispersion. This material ensures excellent optical performance and durability.

The SLB-20B-50PIR1 comes with a front and back coating of opt ir1. This coating enhances the lens's performance by reducing reflection and increasing transmission, thereby improving the overall efficiency of the optical system.
