NanoScan 2s Pyro/9/5 Scanning slit profiler FAQ

Where is the detector in the NanoScan?

The detector is mounted internal to the NanoScan behind the rotating slits. This position is not important to the measurements. The measurement plane is the scan plane of the slits, which is nominally 0.74mm +/-0.025 mm from the Reference Surface on the front of the NanoScan. Please refer to the mechanical drawings in Appendix B of the NanoScan Operational Manual.

Why is the silicon NanoScan not recommended for 1064nm beam measurements?

The silicon detector is very transparent to NIR light >1000nm. If it is used for measuring these beams, you will often see a tailing profile, because the signal does not decay fast enough. This will lead to erroneous results. We recommend using the germanium, or if there is enough power, the pyro electric detector for these wavelengths.

After setting up the NanoScan profiler and acquiring the beam, the profile is bouncing back and forth.

This is usually caused by the Automatic ROI selection. After acquiring the beam, you should then uncheck the Auto ROI in the ROIs menu and the beam should stabilize.

Won't the NanoScan slit diffract the beam?

Yes, but since the NanoScan measures all the light on the detector as a function of slit position, this does not affect the measurement results.

My NanoScan system is giving me an error that says” The selected speed could not be set within 0.01%!” What does this mean?

This means that the motor is not able to set the rotation speed to within 0.01% precision. This typically means that the motor is wearing out, or that something is causing the motor to not be able to rotate at a constant speed. This typically requires that the system come back to the factory for inspection and repair.

This could also mean that you are running the wrong software. If the NanoScan does not have a Mini USB connection on the head, it should not be run on NanoScan 2.4.X software. It should be run on version 2.1 SR1 software.

Can multiple NanoScans be run from the same PC, or can you connect multiple NanoScans and select the one you want to run?

Actually, only one NanoScan can be run from the NanoScan software at a time. If you did connect multiple NanoScans, only one will be recognized and able to run, and the other(s) will not be selectable.
