111-0430E 38.1 mm Dia. x 400 mm FL; Uncoated; Double-Convex Lens

This is a 38.1 mm diameter, double-convex lens, designed for use in optical systems requiring a high degree of precision and clarity. The lens is sourced from EKSMA Optics, a reputable vendor known for their quality optical components.

The lens is made from BK7 Schott, a popular optical glass due to its excellent optical properties and high chemical resistance. It features a double-convex shape, meaning both sides of the lens are curved outwards, which is ideal for focusing light. The lens has a center thickness of 5 mm and an edge thickness of 4.1 mm, providing a robust structure while maintaining a sleek profile.

The effective focal length (EFL) of this lens is 400 mm, which is the distance from the lens center to the point where the light rays converge. This makes it suitable for applications requiring moderate to high magnification. The radii of curvature for the first and second surfaces are 414.1 mm and -414.1 mm respectively, indicating a symmetrically curved lens.

Notably, this lens is uncoated. While coatings can enhance the performance of lenses by reducing reflections and increasing transmission, uncoated lenses can be advantageous in certain applications due to their lower cost and simpler maintenance.
