WebThey are called "Laser Scan Analyzer" because LSA modules are usually used in various applications to measure powers in conjunction with laser scanning/sweeping. They consist of high-speed power meters used to measure powers with synchronized high-speed laser sweeping. More distinctively, LSA provides wavelength measurement for sweeping laser. WebThe PHI 680 system consists of a field-emission scanning electron microscope with a Schottky emission cathode, a secondary electron detector, and an axial cylindrical mirror analyzer with a multi-channel detector to collect Auger electrons produced during electron imaging. Very small spot sizes can be realized with this instrument, down to 7 nm.
