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.

Was this FAQ helpful to you? yes no

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.

Was this FAQ helpful to you? yes no

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.

Was this FAQ helpful to you? yes no

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.

Measuring Astigmatism the Easy Way

Simple NanoScan/BeamScan Measurements ofLaser Diode Beams Produces Astigmatism DataAstigmatism measurements of laser diodes, optical elements, and/or other sources can be made quickly and easily using a NanoScan/BeamScan. For example, by simply focusing the beam from a laser diode onto the profiler and measuring the distance between primary and secondary foci, an indication of source astigmatism is readily obtained. However, since this distance is on the order of 10 microns (μm), longitudinal magnification can be used to accommodate this measurement and reduce potential errors. This method Read more...

Making High Power Measurements with Little to No Attenuation

High power is a fairly indistinct term that means different things in different contexts. High power laser beams are handled by using reflective materials, and the level of reflectivity is dependent on the wavelength of the laser light.  Read more...

Upgrading NS v2 software from Standard to Professional

The NS v2 software is the same for both Standard and Professional, no need to download/install a different version. To perform the upgrade you must purchase the license for the NS v2 Professional.

ISO compliance of non-contact, real-time beam analysis

1. IntroductionDuring the past decade laser power levels used in production applications has risen significantly. Today, welding systems are commonly using laser power in the range of multiple kilowatts. To deliver continuously high product quality, the key parameters of the laser beam must be measured on a regular basis. Ophir has tackled the task and developed a non-contact measurement technology based on the Rayleigh scattering. The technology used in the BeamWatch laser beam profilers enables the measurement of high-power beams without ever touching the laser beam. As the technology is Read more...
