Abstract

The micro optical micro lens comprises: a lens barrel. In the lens barrel, there is a first lens, a first pressure ring, a field mirror, and a second pressure ring in which a magnifier is mounted sequentially mounted. Said first lens is a concave convex lens with a plane table around it; the plane table is supported by the first pressure ring.

Description

Technical field: [0001] The invention relates to an optical lens. Background technique: [0002] Optical lens is the core component of video products such as mobile phones, monitors, monitoring system series products, digital cameras, digital video cameras and other optoelectronic products.
