SLB-15B-25NIR2 15.0 mm Dia. x -24.7 mm FL; Coated; Double-Concave Lens 750-1550nm

The SLB-15B-25NIR2 is a high-quality double-concave lens, 15.0 mm in diameter, designed for use within the wavelength range of 750-1550nm. This lens is sourced from the reputable optical components manufacturer, OptoSigma. The lens features a base shape of a circle and is constructed from the material n-bk7 schott, a popular choice for its excellent optical properties.

The lens has a center thickness of 2mm and an edge thickness of 4.2mm, providing a robust structure while maintaining a sleek profile. The effective focal length (EFL) is -24.7mm, and the radii of curvature for the first and second surfaces are -25.95mm and 25.95mm, respectively. The back focal length (BFL) is -25.3mm, and the lens does not have any inner or outer radius specified, indicating a uniform curvature across the surfaces.

The SLB-15B-25NIR2 comes with a coating of opt ir2 on both the front and back surfaces, enhancing its performance within the specified wavelength range. This lens is an ideal choice for applications that require a concave-concave spherical lens with a wide spectral range and high-quality coating.
