High Resolution Meets Deep Cooling in Laser Beam Profiling
What happens when high-resolution beam profiling is combined with true sub-zero detector cooling?
Duma Optronics BeamOn-TEC was developed to answer exactly that question.
BeamOn-TEC combines:
🔹 8.3 MP high-resolution imaging
🔹 Small-pixel spatial resolution for revealing fine beam structure
🔹 Active TEC cooling of the detector to sub-zero temperatures
🔹 Significantly reduced dark current and thermal noise
🔹 Improved signal-to-noise ratio
🔹 Better visibility of weak beam wings and low-intensity features
🔹 Greater measurement stability and repeatability
Based on our current review of commercially available laser beam profilers, we are not aware of another camera-based beam profiler combining this level of spatial resolution with active TEC cooling of the detector to sub-zero temperatures.
There are cooled beam profilers on the market, particularly for InGaAs/SWIR applications. However, these typically use much lower-resolution detector arrays and, in examples we reviewed, stabilize the detector around +5°C rather than operating it at deep sub-zero temperature.
There are also high-resolution megapixel beam profilers available, but these generally do not combine that resolution with deep active detector cooling.
Why does this matter?
For precision beam profiling, particularly when examining strongly attenuated beams, weak beam wings, low-intensity structures, hot spots, or subtle changes in spatial energy distribution, the detector noise floor matters.
Cooling the detector is not simply about keeping the camera temperature stable.
It is about seeing more of the beam and less of the camera.
That is the idea behind BeamOn-TEC from Duma Optronics.
High resolution. Sub-zero detector cooling. Ultra-low noise. Precision beam profiling.
