SLB-20-60PIR2 20.0 mm Dia. x 60.0 mm FL; Coated; Plano-Convex Lens 750-1550nm
The SLB-20-60PIR2 is a Plano-Convex lens, a type of spherical lens, sourced from OptoSigma. This lens boasts a diameter of 20.0 mm and a focal length of 60.0 mm, making it suitable for a wide range of optical applications. The lens is made from n-bk7 schott, a high-quality optical glass, and features a Plano-Convex geometry, which is characterized by one flat surface and one curved surface.
The lens's geometry includes a thickness edge of 2.0 mm and a thickness center of 3.6 mm. The effective focal length (EFL) is 60.0 mm, and the radius of curvature (R1) is 31.14 mm. The back focal length (BFL) is 57.6 mm, and both the inner and outer radii are 0 mm.
The SLB-20-60PIR2 is coated with Opt IR2 on both the front and back surfaces, enhancing its performance in the 750-1550nm wavelength range. This coating ensures high transmission and low reflection, making the lens ideal for use in infrared (IR) applications.
