84-377 3mm Dia. x -6 FL; VIS 0deg Coated; Plano-Concave Lens 425-675nm

The 84-377 is a 3mm diameter Plano-Concave Lens with a focal length of -6, sourced from the renowned optical components vendor, Edmund Optics. This lens is designed for use within the visible light spectrum, specifically between 425-675nm, making it suitable for a wide range of optical applications.

The lens is fabricated from n-sf11 Schott, a high-index glass material known for its excellent optical properties. The base shape of the lens is circular, and it features a planar front surface and a concave rear surface. The lens has a thickness of 1.17mm at the edge and 1mm at the center, providing a balanced profile for efficient light transmission.

The 84-377 is equipped with a standard Vis-0 coating on both the front and back surfaces. This coating, provided by Edmund Optics, is designed to enhance the lens's performance within the visible light spectrum, offering improved transmission and reduced reflection.

The lens's geometry includes an inner radius of 0mm and an outer radius of 0mm, indicating a simple, straightforward design. The effective focal length (EFL) is -6, and the back focal length (BFL) is -6.56, providing a concave lens with a strong focusing power.
