1 The minimum beam diameters are specified for a precision of measurement better than 1%. Smaller beam diameter can be measured but the error will progressively increase.

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 (OD3). Additional filters with different specifications can be ordered (OD1 to OD4). Delivered with a pair of individual protection caps

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

Vacuum compatible versions up to 10-8 mbar: Possibility to place the BeamPro and perform measurements directly inside a UHV vacuum chamber (not available for all models, please contact us for details)

Trigger: Synchronization of the BeamPro detection to an external signal for accurate laser single pulse measurement
