SLB-25B-50PIR1 25.0 mm Dia. x 50.8 mm FL; Coated; Double-Convex Lens 633-1064nm
The SLB-25B-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 25.0 mm and a thickness edge of 2.0 mm, ensuring durability and robustness. The thickness center is 5.1 mm, providing a balance between weight and optical performance. The effective focal length (EFL) of this lens is 50.8 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 values contribute to the lens's double-convex geometry, which is known for its excellent focusing capabilities. The back focal length (BFL) of this lens is 49.2 mm, which is an important factor to consider when designing an optical system.
The lens is made from n-bk7 schott, a popular material in the optical industry due to its excellent optical properties. The lens is coated with opt ir1 on both the front and back, enhancing its performance in the specified wavelength range.
