47-889-INK 20.0mm Dia. x 70.0mm FL; VIS 0deg; Inked; Plano-Convex Lens VIS 0° 425-675nm
The 47-889-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 20.0mm, is designed for use within 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, providing standard anti-reflection properties.
The lens has a thickness of 1.59mm at the edge and 3.0mm at the center, with an effective focal length (EFL) of 70.0mm. The front surface has a radius of curvature (R1) of 36.18mm, and the back focal length (BFL) is 68.03mm. The lens is made from n-bk7 schott, a common optical glass with high homogeneity and low optical dispersion.
This lens is inked, indicating that it has been marked or labeled for identification or tracking purposes. The lens is circular in base shape and has no inner or outer radius, suggesting it is a simple, single-element lens.
