111-0422E 38.1 mm Dia. x 250 mm FL; Uncoated; Double-Convex Lens
The 111-0422E is a high-quality double-convex lens, sourced from EKSMA Optics, a renowned vendor in the optical components industry. This lens is characterized by its spherical shape and circular base, with a diameter of 38.1 mm and a thickness at the edge of 3.6 mm. The lens's center thickness is 5 mm, providing a robust structure for various applications.
The lens's effective focal length (EFL) is 250 mm, making it suitable for applications that require a longer focal length. The first radius of curvature (R1) is 258.5 mm, while the second radius (R2) is -258.5 mm, indicating the double-convex nature of the lens. The inner and outer radii are 0 mm, suggesting a symmetrical design.
The lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range. The lens is uncoated, which may be suitable for applications where anti-reflection coatings are not required or preferred.
