SLB-20-80PIR1 20.0 mm Dia. x 80.0 mm FL; Coated; Plano-Convex Lens 633-1064nm
The SLB-20-80PIR1 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 80.0 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 features a Plano-Convex geometry, meaning one side is flat (Plano) and the other side is curved (Convex). The thickness at the edge of the lens is 2.0 mm, while the thickness at the center is 3.2 mm. The effective focal length (EFL) of the lens is 80.0 mm, and the radius of curvature (R1) is 41.52 mm. The back focal length (BFL) is 77.9 mm, and both the inner and outer radii are 0 mm.
The SLB-20-80PIR1 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 makes the lens ideal for applications that involve infrared light, such as thermal imaging or night vision systems.
