[0002] In the infrared evaluation system, the blackbody furnace's radiation surface faces downward and is connected to a large-aperture collimator. The collimator is an optical system used to project the image of a reference target from optical infinity to the imager under test. When testing the infrared imaging device, the device's lens needs to be aligned with the imaging port on the left side of the collimator.

[0003] The caliber and length of the collimator vary depending on the focal length of the infrared imaging device being tested. To meet laboratory testing needs, the infrared evaluation system is also equipped with a small collimator.
