SLB-25.4B-40PIR1 25.4 mm Dia. x 41.0 mm FL; Coated; Double-Convex Lens 633-1064nm
The SLB-25.4B-40PIR1 is a high-quality lens from OptoSigma, designed for use in the 633-1064nm wavelength range. This lens is a spherical, biconvex design, made from n-bk7 schott material, which is known for its excellent optical properties.
The lens has a diameter of 25.4mm and a thickness of 1.9mm at the edge, increasing to 5.9mm at the center. The effective focal length (EFL) of the lens is 41mm, making it suitable for a wide range of optical applications. The front and back surfaces of the lens are coated with opt ir1, which enhances its performance in the infrared region.
The curvature of the lens is defined by radii of 41.52mm on both the front and back surfaces, resulting in a back focal length (BFL) of 39mm. The lens does not have any inner or outer radius, indicating a uniform curvature throughout.
The lens is currently in stock and can be purchased directly from the OptoSigma website. With its high-quality construction, broad wavelength compatibility, and precise optical properties, the SLB-25.4B-40PIR1 is an excellent choice for a wide range of optical systems and applications.
