The performance of a laser in practical applications is critical in the designof optical systems and focusing applications, and it can be quantified by measuring M2, the laser beam quality factor, which indicates how close a laser is to being an ideal Gaussian beam. The Beamage-M2 acquires a sequence of beam profile measurements to automatically perform beam quality measurements within a few seconds. It is equipped with the largest optics on the market for easy alignment and fast measurements that you can trust. Its software is both intuitive and ISO compliant.
Manage the Wavelength
Since CMOS sensors are not sensitive to every frequency of the electromagnetic spectrum, we offer several wavelength management solutions to enhance the capabilities of the Beamage beam profiling cameras.
Manage the Beam Size
We offer a simple solution for those who need to profile beams that are larger than the CMOS sensor (>11.3mm x 11.3mm). This solution is a beam-reducing optical component called a CAMERA LENS. It works either by indirectly imaging the transmission of the beam after it has passed through a diffusing element or by directly imaging the beam that is incident on a Gentec-EO detector or beam pump.
Manage Your Laser Power
CMOS sensors have low saturation levels as well as low damage thresholds. It is very important that you control your laser power to get the best measurement possible and avoid damaging the Beamage camera.
- For laser power under 1W, you can attenuate the beam with ND filters
- For laser power up to 1000W, you can sample a small fraction of the beam with a BA optical sampler.
