The SLB-50.8-200PIR1 is a Plano-Convex Spherical Lens, 50.8 mm in diameter, with a focal length of 200.0 mm, sourced from OptoSigma. This lens is designed for use within the wavelength range of 633-1064nm, making it suitable for a variety of applications in the near-infrared spectrum.
The lens is crafted from n-BK7 Schott, a high-quality borosilicate glass known for its excellent optical properties. The Plano-Convex geometry, with a 2.9 mm edge thickness and a 6.1 mm center thickness, ensures efficient light transmission and minimal distortion. The lens's effective focal length (EFL) is 200 mm, and its back focal length (BFL) is 196 mm, providing a wide field of view and a clear image.
The lens features a coating of Opt IR1 on both the front and back surfaces. This anti-reflection coating is specifically designed to reduce surface reflections and increase transmission within the specified wavelength range. The coating ensures optimal performance and reduces the need for additional light management components.
