The SLB-60B-70PM is a high-quality double-convex lens, boasting a diameter of 60.0 mm and a focal length of 72.7 mm. This lens is sourced from OptoSigma, a renowned vendor known for their precision optical elements. The lens is made from n-bk7 schott, a material widely used in optical applications due to its excellent optical properties.
The lens features a spherical shape, with both surfaces being convex. The first surface has a radius of curvature of 72.66 mm, while the second surface has a radius of -72.66 mm. This specific curvature allows for superior light gathering and focusing capabilities. The lens has an edge thickness of 3 mm and a center thickness of 16 mm, providing robustness and durability.
The SLB-60B-70PM is coated with opt m on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission, particularly within the wavelength range of 400-700 nm. The effective focal length (EFL) of the lens is 72.7 mm, and the back focal length (BFL) is 67.3 mm.
This lens is ideal for applications that require high-quality imaging and light transmission within the specified wavelength range. Its robust construction, coupled with its superior optical properties, makes it a reliable choice for various optical systems.
