SLB-50.8-400PM 50.8 mm Dia. x 400.0 mm FL; Coated; Plano-Convex Lens 400-700nm
This is a Plano-Convex lens, type SLB-50.8-400PM, sourced from OptoSigma. The lens has a diameter of 50.8 mm and a focal length of 400.0 mm, making it suitable for a wide range of optical applications. The lens is made from n-bk7 schott material, a popular choice due to its excellent optical properties and high damage threshold.
The lens features a Plano-Convex geometry, meaning one side is flat (Plano) and the other side is curved (Convex). The radius of curvature for the curved side is 207.6 mm, and the lens has an effective focal length (EFL) of 400 mm. The thickness at the edge of the lens is 3 mm, while the thickness at the center is 4.5 mm. The lens does not have any inner or outer radius.
The lens is coated with Opt M on both the front and back surfaces, enhancing its performance in the 400-700 nm wavelength range. This coating helps to reduce reflection and increase transmission, making the lens more efficient in transmitting light.
The lens is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website using the provided weblink.
