Real Time M2 Measurement
Photon Inc
The ModeScan Model 1780 is a laser beam profiling instrument that measures the M2 Beam
Propagation Ratio and all associated ISO 11146 parameters instantaneously in real time at video
rates to over 20Hz.
The CCD is sensitive from ~250nm to 1100nm wavelengths. The standard configuration is supplied with a glass OD 2.8 C-mount neutral density filter for wavelengths >380nm, and an OD 3.0 Fused Silica Inconel neutral density filter for wavelengths <380nm.
The ModeScan 1780 operates under the FireWire BeamPro Acquisition and Analysis Software.
