Description
M2 measurement system “CAM SQUARED”, the latest product from Imagine Optic, offers precise and reliable analysis of laser beam quality with new records in M squared calculation speed and simplicity over other systems.
The standard ISO 11146 requires intensity distribution in at least 10 observation planes from which is computed the M squared factor. They are usually acquired using a camera moved along the optical axis. Imagine Optic proposes an innovative approach allowing the acquisition of the complete dataset needed in only one shot.
Best for: Easy & Quick laser quality testing
+ No need for translation stages
+ No need for alignment
+ No need for focusing optics that can compromise real M2 value

Features
CAM SQUARED performs multiple measurements:
- M2
- Divergence
- Focus diameter
- Waist position
- Rayleigh length
- Thermal effects
- Astigmatism
- Follow the reconstruction of the M2 factor from at least 10 observation planes as recommended in the Standard ISO10116
Applications
Laser beam quality testing is of utmost importance in many laser-based 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.
