The SLSQ-40-220P is a Plano-Convex Lens, a type of spherical lens, sourced from OptoSigma. This lens, with a diameter of 40.0 mm, is designed for use in systems that utilize a wavelength of 546.1 nm. The lens is made from fused silica, a material known for its high transparency and excellent thermal stability.
The lens's geometry is characterized by its edge thickness of 2.0 mm and center thickness of 4.0 mm. The effective focal length (EFL) of this lens is 220.0 mm, which is the distance from the lens's center to the focal point. The radius of curvature (R1) is 101.2 mm, and the back focal length (BFL) is 217.3 mm. The lens's base shape is circular, and it does not have any coating.
The SLSQ-40-220P is available for purchase from the OptoSigma website, where it is listed as in stock. This lens is a versatile and high-quality option for optical systems that require a Plano-Convex lens with the specified parameters.
