L-MPX002 2.8 mm Dia. Plano-Convex Lens; EFL=2.5mm Uncoated

The L-MPX002 is a 2.8 mm diameter Plano-Convex lens, part of Ross Optical's extensive micro-optics catalog. This lens is designed with a spherical shape, featuring a convex surface that refracts light towards a central focal point. The lens is uncoated, meaning it does not have any additional layers to enhance light transmission or protect the surface.

The lens's geometry includes a 0.4 mm thickness at the edge and a 1.5 mm thickness at the center. The effective focal length (EFL) is 2.5 mm, which is the distance from the lens's center to the point where light rays converge. The radius of curvature (R1) is 1.292 mm, and the back focal length (BFL) is 1.5 mm. The lens is made of n-BK7 Schott, a popular optical glass known for its excellent optical properties.

This lens is designed to work with light of a specific wavelength, 587.6 nm, which is in the yellow-green part of the visible light spectrum. It's important to note that the lens's performance can vary depending on the light's wavelength and the angle at which it strikes the lens.
