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.


Optional Features

Windowless: Removal of the BeamPro sensor window to avoid potential interferences

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 (120 dB): Software mode to increase the dynamic of the BeamPro signal acquisition from 14 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
