SLB-50B-80PIR1 50.0 mm Dia. x 81.8 mm FL; Coated; Double-Convex Lens 633-1064nm

The SLB-50B-80PIR1 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 50.0 mm and a thickness edge of 3.0 mm, ensuring durability and robustness. The thickness center measures 10.7 mm, providing a balance between weight and optical performance. The effective focal length (EFL) of this lens is 81.8 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 83.04 mm and -83.04 mm respectively. These values 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 the lens is 78.2 mm, which should be considered when designing the optical system.

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 lens is coated with opt ir1 on both the front and back surfaces, enhancing its transmission characteristics within the specified wavelength range.
