Ophir Photonics Group Introduces Fast, Automated, CO2 Laser Beam Propagation Analyzer for M2 Measurements
Ophir Photonics Group announces the NanoModeScan M2 Laser Beam Propagation Analyzer. NanoModeS- can enable the quantitative measurement and viewing of high power CO2 laser beams. The system is easy to setup and align; the straight line of sight design means little or no attenuation is required.
Nano“It is important to understand variations in the production process,” stated Allen Cary, Sales and Marketing Manager, Ophir-Photon LLC. “The faster laser beam parameters can be quantified and documented, the quicker adjustments can be made to maintain product quality and reduce downtime. NanoModeScan is a valuable tool in this process because its rapid update rates allow for real-time adjustments and it’s comprehensive set of measurements meet quality control requirements.”
The NanoModeScan M2 combines the flexibility and speed of Photon Inc.’s NanoScan near-field profiler with dedicated M2 measurement hardware and software. The system provides automated measurement of M2 in as little as 20 seconds using either the ISO 11146 or Rayleigh method. It reports such parameters as M2 times diffraction limit, K beam propagation factor, d0 beam waist size, Z0 beam waist location, ø divergence, and Zr Rayleigh range.
The NanoModeScan’s software controlled variable scan speed allows the measurement of both CW and kHz pulsed lasers, covering the entire wavelength range from UV to FIR. Rapid beam finding and auto ranging speed up the total M2 measurement to ~20 seconds for CW lasers.
Both 200mm and 400mm lenses are available to generate the proper artificial waist for the laser source under test. For ease of alignment, the system includes an entrance iris on the op- tical axis and a precision alignment stage for horizontal and vertical positioning.
