Title:
OPTICAL FILTER AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2008/038800
Kind Code:
A1
Abstract:
An optical filter (10) is composed of a flat plate (11), a turning pin (12) and an
operation pin (13). The flat plate (11) is provided with a transparent substrate
(31), a resin layer (32) formed on the transparent substrate (31), and a CNT layer
(33) formed on the resin layer (32). The CNT layer (33) is arranged on an uppermost
layer. Since CNT dispersed in the CNT layer (33) has a characteristic of more
absorbing light having a short wavelength, strength of ultraviolet reaching
the resin layer (32) can be reduced by forming the CNT layer (33) on the uppermost
layer, and dye dispersed in the resin layer (32) is prevented from deteriorating.
Thus, the optical filter (10) is provided with excellent resistance to environment.
