45-297 25mm Dia. x 40mm FL; MgF2 Coated; Double-Convex Lens MgF2 400-700nm
This is a 25mm diameter, double-convex lens with a focal length of 40mm, designed for use in the visible spectrum, specifically between 400-700nm. The lens is sourced from Edmund Optics, a reputable vendor in the optical industry.
The lens is made from N-BK7 Schott, a popular glass type known for its excellent optical properties. It features a double-convex geometry, meaning it has two spherical surfaces that curve outwards. This design is often used to reduce spherical aberration and increase the overall image quality.
The lens has a center thickness of 5.3mm and an edge thickness of 1.34mm, providing a robust structure while maintaining a relatively compact form factor. The effective focal length (EFL) is 40mm, which is the distance from the lens's secondary focal point to the lens center.
The lens is coated with MgF2, a type of anti-reflective coating that is standard across many optical applications. This coating helps to reduce surface reflections, improving light transmission and enhancing the overall performance of the lens.
