OPTICAL SYSTEM FOR REINFORCING OPTICAL TWEEZERS CAPTURING FORCE

摘要

An optical system for reinforcing optical tweezers capturing force capable of reliably capturing small underwater article in a non-contact and non-invasive manner by laser beam. This optical system for reinforcing optical tweezers capturing force is an optical tweezers optical system which controls the spherical aberration of a collector lens by disposing an additional lens system movable on the optical axis between a laser beam source and the collector lens and moving the additional lens system on the optical axis.
