C A M SQUAREDAPPLICATIONS

A great choice for almost
any lab or industrial
application, the C A M
SQUARED is Imagine
Optic’s innovative answer
to the need for laser
quality testing and M2measurement.
Finally an M2 meter as easyand quick to set up as abeam profiler.

Preliminary

Laser beam quality testing is of utmost importance in many laserbased applications where beam waist and beam divergence matter:+ Manufacturing, machining, welding for fluence+ Imaging, for resolution+ Fiber optics, for coupling+ Free space optical communications and laser radar systems (LIDAR)
for better propagation through turbulent atmosphere.
CAM SQUARED performs multiple measurements : M2, divergence,focus diameter, waist position, Rayleigh length, thermal effects.

FEATURES+ ISO 11146 standard compliant. The measurement of intensity
combined with phase allows to generate 10 to ∞ of intensity frames
from which is calculated the M2 factor, such as described in the ISO11146 standard.
+ Self aligned. CAM SQUARED requires no alignment, making setup
quick and easy.
+ Short measurement cycle. C A M SQUARED requires notranslation, making measurement cycle very short and the solution
perfectly adapted to pulsed lasers and dynamic applications.​+ Optics free. As no mirrors nor lenses are necessary, there are nooptics introducing aberrations which impair the beam quality. Thereare also no coatings limiting the range of use of the sensor.
+ SM1 thread on the front of the sensor for easy mounting of opticaldensities in order to adapt to the power of the laser to be tested.
