38-291-INK 12.5mm Dia. x 30.0mm FL; VIS 0deg; Inked; Plano-Convex Lens VIS 0° 425-675nm
The 38-291-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 12.5mm, is designed for use in the visible light spectrum, specifically at a wavelength of 587.6nm. The lens has a front and back coating of edm vis-0 std curve, which is a standard coating for this type of lens.
The lens has a thickness of 1.39mm at the edge and 2.7mm at the center, with an effective focal length (EFL) of 30mm. The radius of curvature for the first surface (R1) is 15.51mm, and the back focal length (BFL) is 28.22mm. The lens does not have an inner or outer radius, indicating a uniform curvature.
The lens is made from n-bk7 schott, a common material for optical lenses due to its excellent optical properties. The lens is in stock and available for immediate purchase, as indicated by its weblink status.
