SLB-50B-50PIR1 50.0 mm Dia. x 52.7 mm FL; Coated; Double-Convex Lens 633-1064nm
The SLB-50B-50PIR1 is a high-quality lens offered by 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 50.0 mm and a thickness edge of 3.0 mm, providing a robust structure. The thickness center measures 15.8 mm, indicating a substantial lens body. The effective focal length (EFL) is 52.7 mm, suggesting a moderate focal length for various 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 values indicate a double-convex lens, which is known for its ability to gather and focus light efficiently. The back focal length (BFL) is 47.3 mm, which is crucial for determining the position of the lens in an optical system.
The lens is made of n-bk7 schott material, a common choice for its excellent optical properties. It features a coating of opt ir1 on both the front and back surfaces, enhancing its performance in the specified wavelength range.
