Description
Product Description
- Large-area 1/1.8-inch CMOS sensor, resolution 1600 × 1200, effective pixels 1.92 MP
- Pixel size: 4.5 × 4.5 μm
- Plug-and-play USB3.0 interface; no extra acquisition card required
- Low power consumption, no external power supply needed
- Compatible with continuous and pulsed laser beam profile acquisition
- Pulsed acquisition can be triggered by external TTL asynchronous pulse signals
- Supports “Pass/Fail” (TTL pulse) output; alarms for beam deflection, distortion, defocus, etc., for on-line industrial monitoring
- High SNR of 1000:1, 10-bit AD conversion for rich detail capture
- Patented Oeabt® filter mount supports 1/10~1/100 and 1000× attenuation; beam splitters available for high-power lasers
- Works with Oeabt BeamTester™ software for full-featured beam quality analysis
Laser beam analysis complements power/energy measurements by providing spatial intensity distribution, beam width, centroid, ellipticity, and orientation. BeamTester™ uses a research-grade camera to capture beam profiles and compute over 20 quantitative parameters for accurate beam evaluation, with report generation.

Technical Notes
How to Evaluate Beam Quality
- BeamTester™ generates 2D/3D beam profiles with pseudo-color grading to visualize intensity distribution.
- Real-world Gaussian and flat-top beams are often uneven, tilted, or non-uniform.
Laser Mode Diagrams
- The software clearly shows alignment between lasers and coupling components.
- Different laser types produce distinct profiles; elliptical fitting computes major/minor axes and ellipticity.
Defect Identification
Beams closer to ideal Gaussian or flat-top profiles have fewer defects.
