FAQs and Tech Tips

FAQ

1. What does "relative power meter" mean?

The power meter available as a standard option on silicon and germanium detector NanoScans is a "relative" measurement, which means that the meter is not calibrated to an absolute standard in the factory. You need to measure the source with a calibrated power meter, then input the value into the NanoScan software. The NanoScan will then measure relative to this measured value.

2. Can my NanoScan operate on a Mac?

It is possible to use the NanoScan with a Mac, provide that the Mac has installed the Parallels and Windows operating system available from your Apple dealer. The NanoScan operates under the virtual Windows machine normally.

3. Where is the detector in the NanoScan?

The detector is mounted behind the slits. This position is not important to the measurements. The measurement plane is the scan plane of the slits, which is nominally 1.1mm from the face of the front cap. Refer to the mechanical drawings specific information on the measurement plane location and the reference plane of the scan head.

1. When measuring pulsed beams with the NanoScan,

it is important to input the correct pulse rate into the software. Often this is not the value that the laser manufacturer reports or that the user remembers. For this reason the NanoScan will actually measure and report the pulse repetition rate. Use this number in the software acquisition set up, and the results will be much better.
