SLB-25B-70PIR1 25.0 mm Dia. x 70.7 mm FL; Coated; Double-Convex Lens 633-1064nm
The SLB-25B-70PIR1 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 stability. The thickness center measures 4.2 mm, providing a balanced structure for optimal performance. The effective focal length (EFL) of this lens is 70.7 mm, making it suitable for a variety of optical systems.
The curvature of the lens is defined by its first and second radii, R1 and R2, which are 72.66 mm and -72.66 mm respectively. These values contribute to the lens's double-convex geometry, which is ideal for focusing light. The back focal length (BFL) of the lens is 69.3 mm, and it has no inner or outer radius, indicating a uniform curvature.
The lens is made from n-bk7 schott, a popular material in optical systems due to its excellent optical properties. It is coated with opt ir1 on both the front and back, enhancing its performance in the specified wavelength range.
