LENS WITH IR-CUT FUNCTION

摘要

A lens ( 10 ) and a method for forming the lens ( 10 ). The lens ( 10 ) including a base ( 12 ) with plurality of nano-particles ( 14 ) therein. The base ( 12 ) is made of glass. The nano-particles ( 14 ) can filter infrared rays from incoming light and are evenly distribute throughout the base. The method for forming a lens includes: (1) preparing a glass pre-form ( 60 ) with nano-particles ( 14 ) for filtrating infrared rays; (2) pressing the glass pre-form ( 60 ) using a press mold machine ( 500 ) to mold a lens ( 10 ).
