The SLB-15-40PIR1 is a Plano-Convex lens, a type of spherical lens, sourced from OptoSigma. This lens has a diameter of 15.0 mm and a focal length of 40.0 mm, making it suitable for a wide range of optical applications. The lens is made from n-bk7 schott, a popular material in the optical industry due to its excellent optical properties.
The lens geometry includes a thickness edge of 2.0 mm and a thickness center of 3.4 mm. The effective focal length (EFL) is 40.0 mm, and the radius of curvature (R1) is 20.76 mm. The back focal length (BFL) is 37.8 mm, and both the inner and outer radii are 0 mm.
The SLB-15-40PIR1 comes with a coating on both the front and back surfaces. The coating is opt ir1, which is specifically designed for use in the infrared region of the spectrum, from 633 to 1064 nm. This coating enhances the lens' performance in its intended application range.
