L-MPX004 3 mm Dia. Plano-Convex Lens; EFL=4.5mm Uncoated

The L-MPX004 is a 3 mm diameter Plano-Convex lens, part of the extensive micro-optics range offered by Ross Optical. This lens is designed with a spherical shape and a base shape of a circle, making it suitable for a wide range of applications.

The lens features an effective focal length (EFL) of 4.5mm, providing a moderate level of magnification. The radius of curvature (R1) is 2.3256mm, and the back focal length (BFL) is 3.49mm, contributing to its focusing capabilities. The lens has a thickness of 1.5mm at the edge and 1.8mm at the center, providing a robust structure.

The lens is made from n-BK7 Schott material, a high-quality optical glass known for its excellent transparency and low auto-fluorescence. This material is suitable for use in the visible spectrum, specifically at a wavelength of 587.6nm.

Notably, this lens is uncoated. Coatings are often applied to lenses to reduce reflection, increase transmission, or provide other desirable optical properties. However, the absence of a coating in this case may be desirable for specific applications where the uncoated surface is beneficial.
