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.

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.

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...

Measuring Laser Position & Pointing Stability

One of the laser’s most useful properties is that it can propagate over great distances defining a straight line, and many optical systems are designed to exploit this property. Therefore, beam profilers are often used to verify the performance of lasers and optical systems to avoid problems caused by bad alignment or to streamline the manufacturing processes of these devices. Read more...

Imaging UV light with CCD Cameras

Is it possible to image a UV laser with a Silicon Sensor CCD camera offered by Ophir-Spiricon? The answer is yes, but the direct UV light ablates Silicon CCD chips over time. The ablation is cumulative and depends on the intensity, the wavelength, and the duration of the light on the sensor. The best choice for imaging UV light without damage is to avoid directly imaging the beam on the CCD sensor by using an UV image converter... Read more...

Understanding Dynamic Range…The Numbers Game

There is a fair amount of confusion caused by the reporting of dynamic range of beam profilers. The purpose of this applications note is to explain some of the terminology used in the discussion of this parameter by both Ophir- Spiricon and other suppliers of beam profilers. DefinitionDynamic Range is the ratio of the largest measurable signal to the smallest measurable signal. The smallest measurable signal is typically defined as that equal to the noise level, or alternatively the “Noise Equivalent Exposure” or that point where the Signal-to-noise ratio (SNR) is 1. To Read more...

Laser Beam Measurement Vocabulary

Wavelength: In physics, the wavelength of a sinusoidal wave is the spatial period of the wave— the distance over which the wave's shape repeats,[1] and the inverse of the spatial frequency. It is usually determined by considering the distance between consecutive corresponding points of the same phase, such as crests, troughs, or zero crossings and is a characteristic of both traveling waves and standing waves, as well as other spatial wave patterns.[2][3] Wavelength is commonly designated by the Greek letter lambda (λ)... Read more...
