The SLB-06B-08PIR1 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 6.0 mm and a thickness at the edge of 1.0 mm. The center thickness is 2.1 mm, providing a robust structure for various applications. The effective focal length (EFL) of this lens is 8.4 mm, which is the distance from the lens's center to the focal point when the lens is imaging an object at infinity.
The radii of curvature for the first and second surfaces of the lens are 8.3 mm and -8.3 mm, respectively. The back focal length (BFL) is 7.6 mm, which is the distance from the lens's rear surface to its focal point. The lens is made of n-bk7 schott, a popular optical material known for its excellent optical properties.
The lens is coated with opt ir1 on both the front and back surfaces, enhancing its performance in the specified wavelength range. This coating reduces reflection and increases transmission, making the lens suitable for use in laser applications.
