45-088 12mm Dia. x 30mm FL; MgF2 Coated; Double-Convex Lens MgF2 400-700nm

The 45-088 is a high-quality double-convex lens, sourced from the renowned optical components manufacturer, Edmund Optics. This lens, with a diameter of 12mm and a focal length of 30mm, is designed for use in the visible spectrum, specifically optimized for wavelengths between 400 and 700nm.

The lens is made from Schott's n-BK7 glass, a popular choice for its excellent optical properties and high transmittance in the visible spectrum. The lens features a double-convex geometry, with radii of curvature of 30.36mm for both the front and rear surfaces. This geometry provides a large numerical aperture, making it suitable for a wide range of applications, including imaging, beam shaping, and laser focusing.

The lens is coated with MgF2, a broadband anti-reflective coating that reduces surface reflections and increases transmission. This coating is standard across both the front and rear surfaces, following Edmund Optics' standard curve, ensuring high-quality performance and durability.

The lens has a center thickness of 3.7mm and an edge thickness of 2.5mm, providing robustness and resistance to damage. The effective focal length (EFL) is 30mm, and the back focal length (BFL) is 28.75mm. The lens is circular in shape, with no inner or outer radius specified, indicating a full-circle lens.
