The laser in the infrared tester serves what primary purpose?

Explanation:
The laser in an infrared tester is an aiming aid. It provides a visible cue showing exactly where the sensor is targeting, so you can point the device at the specific spot you want to measure. The temperature reading comes from infrared energy emitted by the object, not from the laser itself. The laser does not calibrate the sensor or generate infrared energy for measurement; calibration is done through internal references and procedures, while the IR energy detected is from the target.
