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.

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

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.

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.

Can I get closer to the front of the NanoScan V2 since it has a new C-Mount adapter ring?

The NanoScan V2 product is great for looking at focused spots, but sometimes the C-Mount ring that is on the front can get in the way mechanically. By removing the three retaining screws it will allow you to remove this ring so you can get mechanically closer to the front of the NanoScan V2. Care should be used when removing these screws and the ring so something does not fall down inside the input aperture of the NanoScan V2. It is recommended that if you are going to remove the C-Mount ring that you invert the NanoScan V2 so it is looking at the floor and then remove the screws and the C-Mount ring to allow gravity to work in your favor and pull them away from the input aperture.

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.
