IRVINE, Calif., Sept. 12, 2019 —  The Infrared Slider from Spectrolight Inc. is a bolt-on accessory for the Light Aligner beam alignment tool.

A screw can be tightened to fix the location of the IR slider based on the required beam height. When the device comes into the path of an IR laser beam, it can be visualized as an orange spot. The wavelength range for detection is between 700 to 1600 nm with a minimum intensity of 3 μW/cm².
