The 47-391-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 40.0mm, is designed for use in the visible to near-infrared spectrum, specifically between 400-1000nm.
The lens has a front (planar) side and a rear (convex) side, both of which are coated with the EDM VISNIR0SP2002000 coating, a broadband anti-reflection coating that enhances transmission in the visible and near-infrared regions.
The lens has a thickness of 3.7mm at the edge and 5.0mm at the center, making it suitable for applications that require a thicker lens. The effective focal length (EFL) of this lens is 300.0mm, and the back focal length (BFL) is 296.7mm. The radius of curvature of the convex side is 155.04mm.
The lens is made of N-BK7 Schott glass, a popular optical material known for its excellent optical properties and high damage threshold. The lens is circular in shape, with no inner or outer radius specified, indicating that it is a full-diameter lens.
This lens is in stock and available for immediate shipping, making it an ideal choice for users who need a high-quality, broadband visible to near-infrared lens promptly.
