SLB-50.8-100NM 50.8 mm Dia. x -100.0 mm FL; Coated; Plano-Concave Lens 400-700nm
This is a Plano-Concave Spherical Lens, type SLB-50.8-100NM, sourced from OptoSigma. The lens has a diameter of 50.8 mm and a focal length of -100.0 mm, making it a negatively powered lens. The lens is made of n-bk7 schott material, a popular choice for its high refractive index and low dispersion.
The lens's geometry includes an edge thickness of 9.6 mm and a center thickness of 3 mm. The front and back surfaces of the lens are coated with an opt m coating, designed to enhance transmission in the 400-700 nm range. This coating improves the lens's performance in visible light applications.
The lens's base shape is circular, and its shape is spherical, which is the most common type of lens shape. The lens's inner and outer radii are both 0, indicating a uniform curvature across the lens surface.
The lens is currently in stock and available for purchase. For more information, please refer to the vendor's website provided in the weblinks section.
