LITTLE ROCK, Ark., Sept. 15, 2010 — For machine vision applications, Power Technology Inc. has announced the PNF laser module designed for 3-D profiling and imaging, dimensional scanning, high-speed road and rail inspection, web inspection, fluorescence and illumination. With its high-quality electronics, it can serve as a drop-in replacement for most existing machine vision lasers. Delivering 0.1 to 200 mW of output power at wavelengths from 375 to 2330 nm, it features uniform non-Gaussian intensity line generators; Variable Focus technology; good wavelength stability; good optical power stability; and continuous-wave, digital or analog modulation up to 100 MHz. The laser module can be configured for optimal performance at close or long range. The Variable Focus technology allows the user to calibrate the focus of the module and then re-tune the line generator for optimal performance. The device offers a choice of 10°, 20°, 30°, 45°, 60° or 90° fan angles, optional collimated output, and electrostatic discharge and overvoltage protection. Analog modulation rate is 20 MHz, analog rise time is >50 ns, digital modulation rate is 100 MHz, and digital rise time is between 1 and 6 ns. The laser module operates from a 5-VDC supply, with a maximum operating current of 250 mA. Operating temperature range is from -10 to 48 °C. It measures 19.07 × 77 mm.
