SLB-05-20PIR1 5.0 mm Dia. x 20.0 mm FL; Coated; Plano-Convex Lens 633-1064nm
The SLB-05-20PIR1 is a Plano-Convex lens, a type of spherical lens, sourced from OptoSigma. This lens has a diameter of 5.0 mm and a focal length of 20.0 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 10.38 mm on the curved side. The lens has an effective focal length (EFL) of 20.0 mm, which is the distance from the center of the lens to the focal point. The back focal length (BFL) is 19.1 mm, which is the distance from the rear surface of the lens to the focal point.
The lens is coated with opt ir1 on both the front and back surfaces. This coating enhances the lens's performance in the infrared region of the spectrum, specifically between 633 and 1064 nm. The coating reduces reflection and increases transmission, making the lens more efficient in transmitting light.
