The 41565 is a Plano-Convex Lens with a diameter of 38.1 mm and a focal length of 125 mm. This lens is sourced from MKS/Newport, a reputable vendor in the optical industry. The lens is uncoated, which means it does not have any additional layers to protect or enhance its optical properties.
The lens's geometry is characterized by its base shape, which is circular, and its thickness. The edge thickness is 1.8 mm, while the center thickness is 5.1 mm. The effective focal length (EFL) is 125 mm, and the radius of curvature (R1) is 57.3 mm. The back focal length (BFL) is 121.5 mm, and the inner radius is 0 mm.
This lens is made of UVFS MAL-1965, a material with a specific refractive index that determines how it bends light. The lens is designed to operate at a wavelength of 589 nm. It is a spherical lens, meaning it has a curved surface that is a portion of a sphere.
