111-0140E 12.7 mm Dia. x 250 mm FL; Uncoated; Double-Convex Lens
The 111-0140E is a high-quality double-convex lens, sourced from the reputable optical components manufacturer, EKSMA Optics. This lens boasts a 12.7 mm diameter and a focal length of 250 mm, making it suitable for a wide range of applications.
The lens is fabricated from BK7 glass, a popular choice in the optical industry due to its excellent optical properties and versatility. The base shape of the lens is circular, and it features a spherical geometry, with a center thickness of 2 mm and an edge thickness of 1.8 mm. The inner and outer radii are 0, and the radii of curvature for the first and second surfaces are 259 mm and -259 mm, respectively.
The lens is uncoated, offering a cost-effective solution for applications where coating is not a necessity. However, it's important to note that uncoated lenses may be more susceptible to environmental factors such as dust and moisture, and may not perform optimally in high-intensity light applications.
