41580 38.1 mm Dia. x 200 mm FL; Uncoated; Plano-Convex Lens
The 41580 is a Plano-Convex Lens, a type of spherical lens, sourced from the reputable vendor MKS/Newport. This lens is characterized by its circular base shape and uncoated surface, making it suitable for a wide range of optical applications.
The lens has a diameter of 38.1 mm and a thickness at the edge of 2.9 mm. The center thickness is 5 mm, providing a robust structure for various optical setups. The effective focal length (EFL) of this lens is 200 mm, making it a medium to long-range focal length lens.
The lens's curvature is defined by a radius of 91.6 mm on the convex side. The back focal length (BFL) is 196.5 mm, and the inner radius is 0 mm. These specifications make the lens suitable for applications requiring a precise focal point and a clear, undistorted image.
The lens is made from UVFS Mal-1965 material, a common choice for optical elements due to its transparency in the visible light spectrum, specifically at the wavelength of 589 nm. This material property ensures high light transmission and minimal chromatic aberration.
