Photon (North Logan, UT) recently announced NanoScan v2, the newest version of the company's scanning slit beam profiler. NanoScan is a NIST-calibrated laser beam profiler. The system uses moving slits to measure beam sizes from microns to centimeters at beam powers from microwatts to kilowatts, with little to no attenuation. The new version adds an enhanced graphical user interface (GUI) with support for the Microsoft(R) Windows ribbon toolbar. Dockable and floatable windows plus concealable ribbon toolbars allow users to make the most of any size display, from small laptops to large, multi-monitor desktops. NanoScan v2 supports both the 64-bit and 32-bit versions of Windows 7, enhancing system configuration options and increasing processing speed. Detector options (silicon, germanium, and pyroelectric technologies) allow measurement at wavelengths from the ultraviolet to the far infrared.
