L-MPC070 4 mm Dia. Plano-Concave Lens; EFL=-55mm Uncoated

The L-MPC070 is a plano-concave lens with a diameter of 4 mm, sourced from the renowned optical components manufacturer, Ross Optical. This lens is designed with a center thickness of 1.5 mm and a focal length of -55 mm, making it suitable for a wide range of applications where negative focal lengths are required.

The lens is fabricated from the high-quality material, N-BK7 Schott, a borosilicate crown glass known for its excellent optical properties, including low dispersion and high transmission across the visible spectrum. This material choice ensures the lens delivers sharp, clear images with minimal chromatic aberration.

The plano-concave geometry of the lens, characterized by a flat (plano) surface and a curved (concave) surface, is ideal for dispersing light and reducing spherical aberration. The lens's inner and outer radii are both zero, indicating a symmetrical curvature that contributes to its high optical performance.

The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties or protect it from environmental factors. However, uncoated lenses can offer superior light transmission and are more cost-effective.
