SLB-50.8-170PIR1 50.8 mm Dia. x 170.0 mm FL; Coated; Plano-Convex Lens 633-1064nm
The SLB-50.8-170PIR1 is a Plano-Convex Lens, part of the Spherical Lens family, sourced from OptoSigma. This lens boasts a diameter of 50.8 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. This material is particularly suitable for applications in the visible and near-infrared spectrum, with a specified wavelength of 546.1 nm.
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, and the lens has an effective focal length (EFL) of 170 mm. The lens's thickness at the edge is 3 mm, while the center thickness is 6.6 mm.
The SLB-50.8-170PIR1 comes with a coating on both the front and back surfaces. The coating is OptoSigma's proprietary Opt IR1 coating, designed to enhance the lens's performance in the infrared region of the spectrum (633-1064 nm). This coating reduces surface reflections, improving the lens's transmission and overall optical performance.
