IR FILTER TEST APPARATUS AND THE METHOD OF TESTING IR FILTER

摘要

An IR filter testing apparatus and a testing method thereof are provided to improve the testing performance of the IR filter reflecting the light of the infrared ray area by photographing the surface of the IR filter through the scan camera and reading the particles. An IR filter testing apparatus is composed of a body(2); a setting board(4) installed at the body to set an IR filter; a cartridge(6) placed at the perimeter part of the setting board to receive the IR filter; a moving unit(8) placed between the setting board and the cartridge to transfer the IR filter; a lamp(10) obliquely mounted at the upper side of the setting board to project the light with a predetermined incidence angle; a scan camera(12) placed on the path of the light to photograph the image of the infrared ray area; and a control part(14) connected to the scan camera to read the image photographed from the scan camera. The setting board is rotatably installed by the driving motor. The IR filter is tested by reading the particles and checking the number of the particles.
