Power Technology has rolled out the new PNF laser module for various machine vision applications, such as illumination, fluorescence, web inspection, high-speed road and rail inspection, dimensional scanning, and 3-D profiling and imaging. The PNF laser module, with high-quality electronics, can be an ideal replacement for most of the current machine vision lasers.
The laser module delivers an output power of 0.1 to 200 mW, at wavelengths ranging from 375 to 2330 nm. It features a maximum analog, digital, or continuous-wave modulation of 100 MHz, better optical power stability and wavelength stability, Variable Focus technology, and line generators having consistent non-Gaussian intensity.
The PNF laser module can be set up to deliver optimal performance, either at long or close range. With the Variable Focus technology, the module enables the user to adjust its focus and re-tune the line generator to deliver optimal performance. The module provides an option of 90°, 60°, 45°, 30°, 20°, or 10° fan angles, overvoltage and electrostatic discharge protection, and optional collimated output.
The module functions from a 5-VDC supply, with an operating current of up to 250 mA. The operating temperature range of the device is -10°C to 48°C. The laser module features analog modulation rate of 20 MHz, and an analog rise time of greater than 50 ns. It also features digital modulation rate of 100 MHz, while the digital rise time of the module is between 1 and 6 ns.
