The SLB-05B-12PIR1 is a high-quality spherical lens from OptoSigma, designed for use in the 633-1064nm wavelength range. This lens, with a base shape of a circle, is a double-convex lens, meaning it has two convex surfaces.
The lens has a diameter of 5.0 mm and a thickness at the edge of 1.2 mm, while the thickness at the center is 1.7 mm. The effective focal length (EFL) of this lens is 12.3 mm, making it a medium to long-focus lens. The first radius of curvature (R1) is 12.46 mm, and the second radius of curvature (R2) is -12.46 mm, indicating the lens's double-convex nature. The back focal length (BFL) is 11.7 mm.
The lens is made of n-bk7 schott, a popular optical glass due to its excellent optical properties and relatively low cost. The lens is coated with opt ir1 on both the front and back, which is ideal for applications that require high transmission and low reflection in the infrared region.
This lens is currently in stock and available for immediate purchase from the OptoSigma website. With its superior optical performance and robust construction, the SLB-05B-12PIR1 is an excellent choice for a wide range of optical applications.
