The 300-0100-00 series 645-nm laser alignment system from Photonic Products offers interchangeable prealigned optics — 88° cross, 58° line, 58° cross/spot — to enable enhanced laser beam performance. The laser intensity is adjustable from 0.1 to 4.5 mW to optimize brightness for the target material. The system incorporates a protective glass window and electronics that are protected from surge, static and reverse polarity. Available in a 14-mm-diameter housing, it is equipped with a 2.1-mm jack connector, a mounting bracket, a wall plug power supply and a power adjustment tool. An optional four-outlet junction box enables up to four modules to be powered from one wall plug. The system has applications in machine vision and the textile industry.
