The SLB-15B-60PIR1 is a spherical lens with a base shape of a circle, offering a diameter of 15.0 mm and a focal length of 60.5 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 62.28 mm for both the front and back surfaces.
The lens has a thickness of 2.0 mm at the edge and 2.9 mm at the center, providing a robust structure. The back focal length (BFL) is 59.5 mm, and the effective focal length (EFL) is the same as the focal length, at 60.5 mm. The lens is coated with opt ir1 on both the front and back surfaces, enhancing its performance in the wavelength range of 633-1064 nm.
This lens is ideal for applications that require a compact, high-performance optical element with a wide range of usability in the infrared spectrum. Its robust construction, coupled with its high-quality coating, makes it a reliable choice for various optical systems.
