Abstract
PURPOSE:To prevent flare and to constitute a lens system whose eccentric accuracy is high, by providing plural grooves on the circumferential surface part of a plastic lens and at least one side of the internal surface part of the lens supporting frame opposed to said circumferential surface part. CONSTITUTION:A reflection preventive means is formed by cutting plural grooves 6 on an outside circumferential surface 1a of a lens supporting part 1b of a plastic lens 1. When constituting a lens system by incorporating into a lens supporting frame 4, the lens supporting surface is supported so as to be opposed to the internal surface part of the lens supporting frame 4, and plastic lenses 1-3 are firmly fixed into the supporting frame 4. In this way, flare is prevented, and a lens system whose eccentric accuracy is high.
