The 47-888-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 performance and durability.
The lens's geometry is characterized by a thickness of 2.84mm at the edge and 4.5mm at the center, with an effective focal length (EFL) of 60.0mm. The radius of curvature for the first surface (R1) is 31.01mm, and the back focal length (BFL) is 57.03mm. The lens does not have an inner or outer radius, indicating a uniform curvature across its surface.
The lens is made from n-bk7 schott, a common optical material known for its high refractive index and low dispersion. This makes the lens suitable for a wide range of optical applications. The lens is inked, a process that aids in identifying and tracking the lens during manufacturing and assembly.
