34-180-INK 40.0mm Dia. x 80.0mm FL; VIS-EXT; Inked; Plano-Convex Lens VIS-EXT 350-700nm
The 34-180-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a base shape of a circle, has a diameter of 40.0mm and a thickness at the edge of 2.84mm, while the center thickness measures 8.0mm. The effective focal length (EFL) of this lens is 80.0mm.
The lens's front and back surfaces are coated with edm vis ext, a type of coating that enhances its performance within the visible light spectrum, specifically between 350-700nm. The radius of curvature for the first surface (R1) is 41.34mm, and the back focal length (BFL) is 74.73mm.
The lens is made of n-bk7 schott, a popular optical glass due to its excellent optical properties and relatively low cost. The lens's geometry does not include an inner radius or an outer radius, indicating a simple, straightforward design.
This lens is a valuable addition to any optical system that requires a plano-convex lens with a wide spectral range and high-quality coatings. It is currently in stock and available for immediate use.
