The SLB-08B-08PIR1 is a high-quality double-convex lens, boasting a diameter of 8.0 mm and a focal length of 8.6 mm. This lens is sourced from OptoSigma, a renowned vendor known for their superior optical elements.
The lens is crafted from n-bk7 schott, a material widely recognized for its excellent optical properties. The base shape of the lens is circular, and it features a spherical geometry. The thickness at the edge of the lens is 1.5 mm, while the center thickness measures 3.6 mm. The effective focal length (EFL) is 8.6 mm, and the radii of curvature are 8.3 mm for the first surface and -8.3 mm for the second surface. The back focal length (BFL) is 7.4 mm.
The SLB-08B-08PIR1 is coated with opt ir1 on both the front and back surfaces, making it suitable for use within the wavelength range of 633-1064nm. This coating enhances the lens' performance by reducing surface reflections and increasing transmission.
