47-870-INK 5.0mm Dia. x 12.0mm FL; VIS 0deg; Inked; Plano-Convex Lens VIS 0° 425-675nm
The 47-870-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 5.0mm, is designed for use within the visible light spectrum, specifically between 425-675nm. The lens features a front and back coating of edm vis-0 std curve, which enhances its performance within this spectrum.
The lens has a thickness of 1.25mm at the edge and 1.77mm at the center, with an effective focal length (EFL) of 12mm. The radius of curvature for the first surface (R1) is 6.22mm, and the back focal length (BFL) is 10.83mm. The lens is made from n-bk7 schott, a popular optical glass due to its excellent optical properties and relatively low cost.
The lens is inked, a process that involves applying a dye to the edge of the lens to indicate its orientation. This is particularly useful during assembly to ensure the lens is positioned correctly.
The item data also indicates that this lens is in stock, making it readily available for immediate use. For more detailed information, the weblink provided leads to the product page on the Edmund Optics website.
