This is a Plano-Convex lens, a type of spherical lens, sourced from Standa. The lens has a circular base shape and is designed for use in the visible light spectrum, specifically at a wavelength of 546 nm.
The lens has a diameter of 50.8 mm and a thickness at the edge of 3 mm. The center thickness of the lens is 5.4 mm. The effective focal length (EFL) of the lens is 250 mm. The radius of curvature for the curved face of the lens is 129.175 mm. The inner and outer radii are both 0 mm, indicating a uniform curvature.
The lens is made of n-BK7 Schott glass, a common material for optical lenses due to its excellent optical properties. The lens does not have any coating, which means it is uncoated. This may affect the lens's performance in certain applications, particularly those requiring high transmission or low reflection.
The lens is in stock and available for purchase. For more information, please visit the vendor's website at http://www.standaphotonics.com/lenses/plano-convex-lenses.php.
