The 110-0104E is a Plano-Convex lens with a diameter of 12.7 mm and a focal length of 20 mm. This lens is sourced from EKSMA Optics, a renowned vendor known for its high-quality optical components. The lens is made of BK7 Schott, a popular glass type in the optical industry due to its excellent optical properties and versatility.
The lens's geometry is characterized by its plano-convex shape, where one side is flat (plano) and the other side is curved (convex). The thickness at the edge of the lens is 2.3 mm, while the thickness at the center is 4.5 mm. The lens's effective focal length (EFL) is 20 mm, which is the distance from the lens's center to the point where light rays converge.
The lens's surface has a radius of curvature of 10.4 mm on the curved side. The inner and outer radii are both 0 mm, indicating that the lens does not have any threading or other features on its edges.
This lens is uncoated, meaning it does not have any additional layers to enhance its optical properties or protect it from environmental factors. However, uncoated lenses can still provide high-quality optical performance, especially in applications where coatings are not necessary or desirable.
The lens is designed to work with a wavelength of 546 nm, a common wavelength used in many optical applications. It is a spherical lens, meaning it has a curved surface that is a portion of a sphere.
