Abstract
A system for aiming a remote IR temperature sensing device includes a laser aiming assembly and a scope assembly mounted to the IR temperature sensing device. The laser aiming assembly provides for adjusting the vertical and azimuthal positions of an alignment beam to facilitate the use of inexpensive, low-tolerance parts while providing high accuracy to improve sensitivity, accuracy, and resolution. The laser aiming assembly includes a laser aiming mirror for directing the alignment beam toward the target. The system includes a beam splitter which reflects incoming visible radiation toward the scope assembly and allows incoming IR radiation to pass through to an IR temperature sensor. The beamsplitter has an opening of sufficient size to allow the alignment beam to pass through unobstructed but not so large as to interfere with the operation of the beamsplitter. The scope assembly provides for magnifying the focal area of the system for enhanced viewing by the user and additionally provides for more efficient and accurate temperature measurement.
