2 Depending on the type of calculation, frame rate may vary.
3 Due to rolling shutter, the actual minimum exposure time to properly capture the whole beam will be limited by the laser beam size (in case of single-shot measurement) or by the laser repetition rate. For single-shot measurement : the larger the beam, the longer the required minimum exposure time. Otherwise, the slower the repetition rate, the longer the required minimum exposure time.

Optional Features
Windowless: Removal of the BeamPro sensor window to avoid potential interferences
UV extension: Increases the BeamPro wavelength range to the UV region, down to 190 nm
Additional ND filters: The default BeamPro configuration includes one ND filter (ND4). Additional filter with different specifications can be ordered
High Dynamic Range: Software mode to increase the dynamic of the BeamPro signal acquisition from 12 to 16 bits. Not compatible with pure single-shot measurement as 2 images are necessary to build one beam profile image
Trigger: Synchronization of the BeamPro detection to an external signal for accurate laser single pulse measurement
