47-907 12mm Dia. x -48 FL; VIS 0deg Coated; Plano-Concave Lens 425-675nm
The 47-907 is a Plano-Concave Lens with a 12mm diameter and a -48 FL (focal length) from Edmund Optics. This lens is designed for use within the visible light spectrum, specifically between 425-675nm. The lens is made from n-BK7 Schott material, a popular choice for its high refractive index and low dispersion.
The lens features a plano-concave geometry, meaning one side is flat while the other is curved inward. The inner radius is 0mm, and the outer radius is also 0mm, indicating a uniform curvature. The lens has a thickness of 4.12mm at the edge and 3.5mm at the center.
The lens is coated with the EDM VIS-0 STD curve on both the front and back surfaces. This coating is designed to improve the lens's performance within the visible light spectrum. The coating status is currently in stock, according to the vendor's website.
