47-331-INK 12.0mm Dia. x 18.0mm FL; VIS 0deg; Inked; Plano-Convex Lens VIS 0° 425-675nm

The 47-331-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 12.0mm, is designed for use within the visible light spectrum, specifically at a wavelength of 587.6nm. The lens features a front and back coating of edm vis-0 std curve, providing standard performance and durability.

The lens has a thickness of 1.41mm at the edge and 3mm at the center, with an effective focal length (EFL) of 18mm. The radius of curvature for the first surface (R1) is 12.11mm, and the back focal length (BFL) is 16.22mm. The lens does not have an inner or outer radius, indicating a uniform curvature.

This lens is made from n-sf5 schott, a high-quality optical material known for its excellent transmission properties and chemical resistance. The lens is inked, which aids in identification and handling. The weblink provided is valid and indicates that the lens is currently in stock, making it readily available for immediate use.
