What Can be Measured?
Measuring high-power beams can be tricky. The lasers have the potential to damage the scan head, and any reflected light can be dangerous to both the operator and the surroundings. The High-Power NanoScan can measure these beams because it uses a combination of highly reflective components with high thermal dissipation capability. It is important to manage the reflected beam so that it neither reenters the laser cavity nor sends stray beams into the surrounding area. The scan head is designed to make short duration measurements to avoid excessive heating of components. The head should be only in the incident beam for 10 to 60 seconds depending on the power levels to prevent excessive heating of the components. The High-Power NanoScan scan head has been shown to be able to handle power densities of 3.2MWcm-2 at 10.6μm, the power density of a 200μm beam at 1kW. At the shorter wavelengths of the other common industrial lasers, Nd:YAG and DPSS, the upper limits are a little less, due to the slightly lower reflectivity of the components at wavelengths around 1000nm. Visible and UV lasers can also be measured, but these will have lower limits yet. The chart below shows the damage thresholds for pulsed beam energies for the three wavelength regimes. The lines represent the maximum energies per pulse for various spot sizes that correspond to 5J/cm2 for the 3μm to 100μm wavelengths, 2.5J/cm2 for the 700nm to 3μm range, and 250mJ/cm2 for the UV-Visible range from 190nm to 700nm. When operating with pulsed lasers, calculate the energy per pulse to ensure that the values fall below these lines for the wavelength of the laser. Operation above these values will likely cause damage to the scan head apertures.

Ordering Information - High Power NanoScan

All High-Power NanoScan Systems Include: Fan cooled scanhead. For use at wavelengths from 200nm to greater than 20μms. Maximum power capacity is dependent on wavelength and spot size. Refer to operating space charts for more information. Slits and scan drum are highly reflective and user must send reflected energy into appropriate dump. A direct back reflection may cause laser cavity to oscillate or if not properly directed may cause damage. User must handle all back-reflected energy from laser. NanoScan Integrated Software package. Software for use with NanoScan under Microsoft Windows 2000 Professional, XP Professional, Vista ,and Windows 7 (32-and 64-bit) operating systems.
Measurements include: spot size, position and position difference information and laser profiles. Includes “peak connect” and software control of scan speed for measurement of pulsed and pulse width modulated (PWM). Software includes ability to capture and record bursts of data and ActiveX automation.
USB 2.0 Controller allows NanoScan to interface to USB 2.0 port of laptop or desktop PC.
Certificate of Calibration traceable to National Institute of Standards and Testing (NIST) to better than ±3%.
