3.4.1 NanoScan 2s 3.4.1.1 NanoScan 2s – Standard Version Scanning Slit Beam Profiler For High Accuracy Dimensional Measurement NanoScan 2s combines the convenience and portability of direct USB connectivity with the speed, accuracy, and dynamic range that users have come to expect from the Photon NanoScan slit based profilers. The NanoScan 2s is available with a silicon, germanium or pyroelectric detector, which allows it to profile lasers of any wavelength from UV to far infrared, out to 100µm and beyond. With the new NanoScan 2s software package, the user can configure the display interface however it is desired; displaying those results of most interest on one easy-to-read screen, or on multiple screens. The NanoScan slit profiler is the most versatile laser beam profiling instrument available today: providing instantaneous feedback of beam parameters for CW and kilohertz pulsed lasers, with measurement update rates to 20Hz. The natural attenuation provided by the slit allows the measurement of many beams with little or no additional attenuation. The high dynamic range makes it possible to measure beams while adjustments to focus are made without having to adjust the profiler. Just aim the laser into the aperture and the system does the rest! NanoScan 2s is a PC-based instrument for the measurement and analysis of laser beam spatial irradiance profiles in accordance with the ISO standard 11146. The scan heads also measure power in accordance with ISO 13694. NanoScan uses the scanning slit, one of the ISO Standard scanning aperture techniques. It can measure beam sizes from microns to centimeters at beam powers from microwatts to over kilowatts, often without attenuation. Detector options allow measurement at wavelengths from the ultraviolet to the infrared. The NanoScan 2s digital controller has 16-bit digitization of the signal for enhanced dynamic range up to 35dB power optical. With the accuracy and stability of the beam profile measurement you can measure beam size and beam pointing with a 3-sigma precision of several hundred nanometers. The software controllable scan speed and a “peak-connect” algorithm allows the measurement of pulsed and pulse width modulated lasers with frequencies of 10kHz and higher*. The NanoScan is also able to measure up to 16 beams, or regions of interest, in the aperture simultaneously. Absolute measurement accuracy is guaranteed by NIST traceable calibration of every NanoScan Measure any wavelength from UV to very far infrared (190nm to >100µm) Instantaneous real time display of results; beam found in less than 300ms and updated at up to 20Hz Waist location can be determined to within ±25µm due to the well-defined Z-axis datum plane of the NanoScan Measure pulsed and CW lasers For pulsed beams the pulse rate is measured and reported From as small as 7µm beams, can be measured directly with guaranteed accuracy and precision Additional high signal to noise ratio can be achieved with averaging Z-axis caustic measurements are available with built-in mechanical linear stage control M2 propagation ratio values available with simple M2 Wizard included with the software. Any beam result can be charted and monitored over time Power levels can be monitored along with spatial measurements to determine if losses are introduced by beam adjustments Log results to text files for independent analysis Automate the system using optional ActiveX Automation commands, available with the PRO version software and scan heads Samples of automation programs included for Excel, VBA, LabView and Visual Basic.net * The minimum frequency is a function of the beam size and the scan speed. This is a simple arithmetic relationship; there must be a sufficient number of pulses during the time that the slits sweep through the beam to generate a meaningful profile.

NanoScan 2s Configurable User Interface In addition to new hardware, the NanoScan 2s has an updated integrated software package for the Microsoft Windows Platform, which allows the user to display any of the results windows on one screen. The NanoScan 2s software comes in two versions, STD and PRO. The NanoScan 2s Pro version includes ActiveX automation for users who want to integrate the NanoScan into OEM systems or create their own user interface screens with C++, LabView, Excel or other OEM software packages.

Integrated Power Meter The silicon and germanium detector equipped NanoScan 2s systems include an integrated 200mW power meter. The scanhead comes with a quartz attenuator window that provides a uniform response across a broad wavelength range. This is a relative power meter that has better than 1.5% correspondence when calibrated with a user-supplied power meter and used in the same configuration as calibrated. The power meter screen in the software shows both the total power and the individual power in each of the beams being measured. % of power within the aperture integrated power measurement...

The Most Versatile and Flexible Beam Profiling System Available With the available range of detectors, slit sizes and apertures the NanoScan 2s provides the maximum versatility in laser beam profiling. NanoScan 2s adds the convenience and portability of direct USB connectivity: no external controllers or power supplies reguired to operate the profiler. In addition the rotation mount has been redesigned to provide a stand for vertical operation, if desired. The mount can be positioned in one of two places. If vertical operation is desired the mount is positioned toward the back of the scanhead...
