48-339 12.0mm Dia. x -18 FL; MgF2 Coated; Plano-Concave Lens 400-700nm

The 48-339 is a plano-concave lens with a diameter of 12.0mm, a focal length of -18, and a central thickness of 3.5mm, making it suitable for applications that require a negative lens. The lens is sourced from Edmund Optics, a reputable vendor known for its high-quality optical components.

This lens is made from n-sf11 Schott, a high-index glass with excellent optical properties. The plano-concave geometry, characterized by a flat front surface and a curved back surface with a radius of -14.12mm, is designed to diverge light. The back focal length is -19.95mm, and the edge thickness is 4.7mm.

The lens is coated with MgF2, a broadband anti-reflection coating that enhances transmission in the 400-700nm spectral range. This coating is standard from Edmund Optics and provides a typical reflectance of less than 1% at normal incidence.

The 48-339 is a versatile lens suitable for various applications, including imaging systems, beam shaping, and laser applications. It is in stock and ready for immediate shipping, making it an ideal choice for users seeking a high-quality, readily available plano-concave lens.
