  • PNF Laser Module
Sep 2010
Power Technology Inc.Request Info
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.

A physical variable that is proportionally similar to another variable over a specified range. An analog recording contains data that is similar to the source.
Denoting the use of binary notation; i.e., the representation of data by bits (1 or 0).
The emission of light or other electromagnetic radiation of longer wavelengths by a substance as a result of the absorption of some other radiation of shorter wavelengths, provided the emission continues only as long as the stimulus producing it is maintained. In other words, fluorescence is the luminescence that persists for less than about 10-8 s after excitation.
The general term for the application of light to a subject. It should not be used in place of the specific quantity illuminance.
