The SLB-20-200PIR2 is a Plano-Convex lens, a type of spherical lens, sourced from OptoSigma. This lens has a diameter of 20.0 mm and a focal length of 200.0 mm, making it suitable for a wide range of optical applications. The lens is made from n-bk7 schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence.
The lens features a Plano-Convex geometry, meaning one side is flat (Plano) and the other side is curved (Convex). The curvature of the lens is defined by a radius of 103.8 mm on the curved side. The lens has a thickness of 2.0 mm at the edge and 2.5 mm at the center. The back focal length (BFL) of the lens is 198.4 mm.
The SLB-20-200PIR2 is coated with Opt IR2 on both the front and back surfaces. This coating enhances the lens's performance in the infrared spectrum, specifically between 750nm and 1550nm. The coating reduces surface reflections, improving the lens's transmission and overall optical efficiency.
