SLB-20-170PIR1 20.0 mm Dia. x 170.0 mm FL; Coated; Plano-Convex Lens 633-1064nm
The SLB-20-170PIR1 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 170.0 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 88.23 mm on the curved side. The lens has a thickness of 2.0 mm at the edge and 2.6 mm at the center. The back focal length (BFL) of the lens is 168.2 mm, and the effective focal length (EFL) is 170.0 mm.
The SLB-20-170PIR1 comes with a coating on both the front and back surfaces. This coating, referred to as opt ir1, is specifically designed for use in the infrared region of the spectrum, between 633 and 1064 nm. This coating enhances the lens's performance in the infrared range, making it ideal for applications such as thermal imaging, night vision, and other infrared-based technologies.
