The SLB-05B-15PIR1 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 1.6 mm. The effective focal length (EFL) of this lens is 15.3 mm, making it suitable for a variety of optical applications. The radii of curvature for the first and second surfaces are 15.57 mm and -15.57 mm, respectively, and the back focal length (BFL) is 14.7 mm.
The lens is made of n-bk7 schott, a popular optical glass due to its excellent optical properties and low cost. The lens is coated with opt ir1 on both the front and back surfaces, enhancing its performance in the specified wavelength range.
