Overview

The NanoScan™ 2s Si/3.5/1.8 scanning-slit profiling system accurately captures and analyzes wavelengths from 190 to 1100 nm with its Silicon detector. It features a 1.8 µm slit size suitable for small beams, near real-time data capture rates, an optional power measurement feature, and operates in CW or kHz Pulsed modes which makes it ideal for comprehensive analysis of UV, Visible, and NIR lasers.

3.5 mm aperture for beam sizes from 7 µm to 2.3 mm
Power levels from 10 nW to 10W
Silicon detector covers 190 to 1100 nm spectral range
USB 2.0 interface
NanoScan Standard or Professional software included

NanoScan 2s Slit Profiler Demonstration

Fundamentals of Laser Measurement & Beam Profiling

Is your laser's beam profile shaped correctly for your application? This video teaches the fundamentals of laser beam profiles and discusses the benefits of profiling your laser beam. Several case studies are presented showing before and after laser beam profiles.

Why Measure Your Laser Beam?

This tutorial is presented by Ophir-Spiricon sales engineers - the experts in the field of measuring lasers and in helping you get the most out of your laser beam.

Frequently Asked Questions

Where is the detector in the NanoScan?
Answer
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 0.74 mm ±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 1064 nm beam measurements?
Answer
The silicon detector is very transparent to NIR light >1000 nm. 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, why is the profile bouncing back and forth?
Answer
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.

Will the NanoScan slit diffract the beam?
Answer
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?
Answer
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.

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

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

I’m using an Automation Interface with my NanoScan 2s system and a new version of NanoScan V2s software is available. If I upgrade to that version, will my Automation Interface still work?
Answer
Yes, the NanoScan Automation Interface is the same between older versions of the application and the most current version. Installing the latest version of the NanoScan V2 application will not break your Automation Interface. You will need to run the NanoScan V2 application one time before attempting to use your Automation Interface again, though. This is to establish the connection with the hardware and the NanoScan V2 application again after the upgrade, so the Automation Interface will be able to get the data from the NanoScan V2 application.
