SLB-25.4-50NIR1 25.4 mm Dia. x -50.0 mm FL; Coated; Plano-Concave Lens 633-1064nm

The SLB-25.4-50NIR1 is a Plano-Concave Spherical Lens, 25.4 mm in diameter, with a focal length of -50.0 mm, specifically designed for use within the wavelength range of 633-1064nm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry.

The lens is constructed from n-bk7 schott material, a popular choice due to its excellent optical properties and versatility. The base shape of the lens is circular, with a thickness at the edge measuring 5.3 mm and a center thickness of 2 mm. The effective focal length (EFL) is -50.0 mm, and the radius of curvature (R1) is -25.95 mm. The back focal length (BFL) is -51.3 mm, and the lens does not have an inner or outer radius.

The SLB-25.4-50NIR1 is coated with opt ir1 on both the front and back surfaces, enhancing its performance within the specified wavelength range. This coating helps to reduce reflection and increase transmission, making it ideal for use in various applications such as laser systems, beam shaping, and imaging systems.
