The SLB-50.8-100PIR1 is a Plano-Convex Spherical Lens, sourced from OptoSigma, with a diameter of 50.8 mm and a focal length of 100.0 mm. This lens is designed for use within the wavelength range of 633-1064nm, making it suitable for a variety of applications within this spectrum.
The lens is fabricated from n-bk7 schott, a popular material in optical applications due to its excellent optical properties. The lens features a Plano-Convex geometry, with a center thickness of 9.6 mm and an edge thickness of 3 mm. This geometry, combined with the lens's diameter and focal length, results in a back focal length of 93.7 mm and an effective focal length of 100 mm.
The lens's surfaces are coated with opt ir1, a coating that is specifically designed for use within the infrared spectrum. This coating enhances the lens's performance by reducing surface reflections and improving transmission within its designated wavelength range.
