SLB-40B-60PIR2 40.0 mm Dia. x 61.4 mm FL; Coated; Double-Convex Lens 750-1550nm
The SLB-40B-60PIR2 is a spherical lens with a base shape of a circle, offering a diameter of 40.0 mm and a focal length of 61.4 mm. This lens is sourced from OptoSigma, a reputable vendor in the optical industry. The lens is made of n-bk7 schott material, a popular choice for its excellent optical properties.
The lens features a double-convex geometry, with radii of curvature of 62.28 mm for both the front and back surfaces. This particular lens has a thickness of 2.0 mm at the edge and 8.6 mm at the center, providing a robust structure suitable for various applications. The back focal length (BFL) is 58.6 mm, and the effective focal length (EFL) is 61.4 mm.
The SLB-40B-60PIR2 is coated with opt ir2 on both the front and back surfaces, making it suitable for use within the wavelength range of 750-1550nm. This coating enhances the lens's performance by reducing surface reflections and increasing transmission, thereby improving overall system efficiency.
