Scanning Slit Optical Beam Profiler
The profiler is ideal for analyzing laser beam profiles that have a close-to-Gaussian beam shape. It allow fast, simultaneous measurements of both the X and Y profiles with a high dynamic range of 78 dB and a variable scanning speed from 2 to 20 Hz without the need of attenuators in the beam path. The profiler is equipped with a physical aperture measuring 9 mm in diameter. This design offers two slit widths, low noise electronics, and the additional knife-edge mode, making it possible to analyze an extended range of beam diameters (2.5 µm to 9 mm) with a single device. The beam diameter is measured in accordance with the ISO11146 standard. It can be displayed using a number of industry-standard clip levels, such as 1/e2 (13.5%), 50%, or an arbitrary clip level set by the user.
