111-0108E 12.7 mm Dia. x 25 mm FL; Uncoated; Double-Convex Lens

The 111-0108E is a high-quality double-convex lens, sourced from EKSMA Optics, a renowned vendor known for their extensive range of optical components. This lens boasts a 12.7 mm diameter and a focal length of 25 mm, making it suitable for a wide range of applications.

The lens is fabricated from BK7 glass, a popular choice due to its excellent optical properties and versatility. The base shape is circular, and the lens features a double-convex geometry, with radii of curvature R1 and R2 measured at 25.3 mm and -25.3 mm respectively. This geometry results in a high refractive power, ideal for imaging and beam shaping applications.

The lens has a thickness of 1.9 mm at the edge and 3.5 mm at the center. The edge thickness, combined with the lens's material, contributes to its robustness and durability. The lens is uncoated, offering a cost-effective solution for applications where coating is not a necessity. However, for applications requiring higher transmission or protection against environmental factors, coating options are available.

The 111-0108E is designed to operate at a wavelength of 546 nm, making it suitable for use in a variety of systems operating in this spectral range. Its high optical quality and precision make it an excellent choice for applications in fields such as metrology, machine vision, and scientific research.
