Structure of the optical system of an infrared camera
Document Type and Number:
Japanese Patent JP6139260
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain an infrared camera having a structure in which a large F value is obtained with an opening diameter as small as possible.SOLUTION: The infrared camera comprises: a condenser lens D for condensing infrared rays; an infrared detector A for detecting infrared rays having passed through the condenser lens D; and a shutter C disposed between the condenser lens D and the detector A and having a blade C3 for performing an opening and closing operation. An opening of a container member C1 for containing the blade C3 in an opened state is formed as an inclined plane S1 along the inclination of a beam bundle L incident to the detector A from the condenser lens D.
