SLB-10B-20PIR2 10.0 mm Dia. x 20.5 mm FL; Coated; Double-Convex Lens 750-1550nm

The SLB-10B-20PIR2 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 10.0 mm and a thickness edge of 2.0 mm, ensuring durability and stability. The thickness center measures 3.2 mm, providing a robust structure for various optical setups. The effective focal length (EFL) of this lens is 20.5 mm, making it suitable for a wide range of applications.

The curvature of the lens is defined by its first and second radii, R1 and R2, which are 20.76 mm and -20.76 mm respectively. These radii contribute to the lens's double-convex shape, which is designed to minimize spherical aberration and provide superior image quality. The back focal length (BFL) of this lens is 19.5 mm.

The SLB-10B-20PIR2 is made from n-bk7 schott material, a popular choice for its excellent optical properties and durability. The lens is coated with opt ir2 on both the front and back, enhancing its performance in the infrared spectrum.
