SLB-25B-30PIR2 25.0 mm Dia. x 31.2 mm FL; Coated; Double-Convex Lens 750-1550nm
The SLB-25B-30PIR2 is a spherical lens with a base shape of a circle, offering a diameter of 25.0 mm and a focal length of 31.2 mm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry. The lens is made of n-bk7 schott, a high-quality optical glass, and features a double-convex geometry, with radii of curvature of 31.14 mm for the first surface and -31.14 mm for the second surface.
The lens has a thickness of 2.0 mm at the edge and 7.2 mm at the center, providing a robust structure. The back focal length (BFL) is 28.8 mm, and the effective focal length (EFL) is 31.2 mm. The lens is coated with opt ir2 on both the front and back surfaces, enhancing its performance in the 750-1550nm wavelength range.
This lens is ideal for applications that require a broad wavelength range and high-quality imaging, such as infrared spectroscopy, beam shaping, and optical fiber coupling. The SLB-25B-30PIR2 is currently in stock and available for immediate purchase, as indicated by its valid weblink status.
