SLB-50.8-250PIR1 50.8 mm Dia. x 250.0 mm FL; Coated; Plano-Convex Lens 633-1064nm
This is a Plano-Convex lens, type SLB-50.8-250PIR1, sourced from OptoSigma. The lens has a diameter of 50.8 mm and a focal length of 250 mm, making it suitable for a wide range of optical applications. The lens is made of n-bk7 schott material, a popular choice due to its excellent optical properties and durability.
The lens features a Plano-Convex geometry, meaning one side is flat while the other is curved. The curvature of the lens is defined by a radius of 129.75 mm, and the lens has a center thickness of 5.4 mm and an edge thickness of 2.9 mm. The lens's effective focal length (EFL) is 250 mm, and the back focal length (BFL) is 246.4 mm.
The lens is coated with opt ir1 on both the front and back surfaces, enhancing its performance in the 633-1064nm wavelength range. This coating helps reduce reflection and increase transmission, making the lens more efficient in its intended use.
