SLB-15B-25NIR1 15.0 mm Dia. x -24.7 mm FL; Coated; Double-Concave Lens 633-1064nm
The SLB-15B-25NIR1 is a high-quality double-concave lens, 15.0 mm in diameter, designed for use in the 633-1064nm wavelength range. This lens is sourced from OptoSigma, a renowned vendor in the optical industry, and is currently in stock, as indicated by its weblink status.
The lens is made from n-bk7 schott, a popular material in the optical industry due to its excellent optical properties. It features a base shape of a circle, with a thickness of 4.2 mm at the edge and 2 mm at the center. The effective focal length (EFL) of this lens is -24.7 mm, making it a double-concave lens. The first radius of curvature (R1) is -25.95 mm, while the second radius of curvature (R2) is 25.95 mm, contributing to its double-concave nature.
The lens comes with a broadband anti-reflection coating, specifically the opt ir1 coating, on both the front and back surfaces. This coating enhances the lens's performance by reducing unwanted reflections and increasing transmission in the specified wavelength range.
