Optical unit using plastic lenses |
abstract |
The present invention provides an optical unit for high-resolution applications all lenses in which are made of plastics. The optical unit includes lens ( 1 ) and ( 2 ). The lens ( 1 ) is a plastic lens having an Abbe number of 45-60. The lens ( 2 ) is a lens injection molded from a polycarbonate material comprising a structure derived from spirobiindan and having a glass transition temperature of 120-150° C. |
