47-881-INK 18.0mm Dia. x 36.0mm FL; VIS 0deg; Inked; Plano-Convex Lens VIS 0° 425-675nm
The 47-881-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 18.0mm, 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 1.25mm at the edge and 3.57mm at the center, with an effective focal length (EFL) of 36.0mm. The radius of curvature for the first surface (R1) is 18.62mm, and the back focal length (BFL) is 33.65mm. 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 adds a dye or pigment to the surface of the lens to enhance contrast and make it easier to handle. This lens is designed for use with a viewing angle of 0 degrees and is suitable for use with light within the 425-675nm range.
