NanoScan2s Ge/9/5
This NanoScan scanning-slit profiling system accurately captures and analyzes wavelengths from 700nm - 1800nm with its Germanium detector. It features an aperture size suitable for most 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 IR and NIR lasers.
Beam Sizes of 20µm to ~6mm
Power Levels of ~10nW to ~10W

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!
Capabilities
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.

* 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. Please refer to Photon’s Application Note, Measuring Pulsed Beams with a Slit-Based Profiler.
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.
Available Detectors
The NanoScan 2s is available with silicon, germanium or pyroelectric detectors to cover the light spectrum from UV to very far infrared.
Apertures and Slits
The NanoScan 2s is available with a variety of apertures and slit sizes to allow for the accurate measurement of varying beam sizes. The slit width defines the minimum beam width that can be measured; due to convolution error, the slit should be no larger than ¼ the beam diameter to provide a ±3% accurate measurement. For this reason the minimum beam diameter measureable with the standard 5µm slit is 20µm. To measure beams smaller than 20µm it is necessary to use the small aperture 1.8µm slit instrument, providing a minimum beam diameter of ~8µm. Because these slits are so narrow, the maximum length limits the aperture to 3.5mm. Contrary to many people’s beliefs, these smaller slits do not improve the resolution of the measurement, only the minimum size of the beam. Therefore, unless it is necessary to measure beams less than 20µm, one would be advised to stick with the 9mm/5µm configurations.
For very large beams, NanoScan is available with a large 20 or 25mm aperture with 25µm slits. These sensor are larger than the standard scan heads (100mm diameter)
