111-0116E 12.7 mm Dia. x 50 mm FL; Uncoated; Double-Convex Lens
The 111-0116E is a double-convex lens with a diameter of 12.7 mm and a focal length of 50 mm. This lens is sourced from EKSMA Optics, a reputable vendor known for its high-quality optical components. The lens is made of BK7 glass, a popular material in the optical industry due to its excellent optical properties and versatility.
The lens features a base shape of a circle, with a thickness of 1.7 mm at the edge and 2.5 mm at the center. The effective focal length (EFL) is 50 mm, making it suitable for various applications that require a moderate focal length. The first radius of curvature (R1) is 51.4 mm, while the second radius (R2) is -51.4 mm, indicating the lens's double-convex shape.
The lens does not come with any coating, which means it is uncoated. This may affect its performance in certain applications, particularly those requiring high transmission or resistance to environmental factors. However, uncoated lenses are often preferred for their simplicity and cost-effectiveness.
