110-5105E 12.7 mm Dia. x 25 mm FL; Uncoated; Plano-Convex Lens
The 110-5105E is a Plano-Convex lens with a diameter of 12.7 mm and a focal length of 25 mm. This lens is sourced from EKSMA Optics, a reputable vendor known for its high-quality optical components. The lens is made of CAF2 (MgF2) material, specifically the Mal-1963 variant, which is well-suited for various applications due to its excellent optical properties.
The lens's geometry is characterized by its plano-convex shape, where one side is flat, and the other side is curved. The thickness at the edge of the lens is 2 mm, while the center thickness is 4.1 mm. The lens's design is spherical, which is a common choice for many optical systems due to its simplicity and versatility.
Notably, this lens is uncoated. While coatings can enhance the performance of lenses by reducing reflections, increasing transmission, or providing other benefits, an uncoated lens can be a suitable choice for certain applications. It may be more cost-effective, or the specific requirements of the application may not necessitate the use of a coated lens.
The lens is designed to operate at a wavelength of 2940 nm. This makes it suitable for applications that use this specific wavelength, such as certain types of spectroscopy or laser systems.
