BTC200 Beam Quality Analysis Camera

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

1. BeamTester™ generates 2D/3D beam profiles with pseudo-color grading to visualize intensity distribution.
2. Real-world Gaussian and flat-top beams are often uneven, tilted, or non-uniform.

Laser Mode Diagrams

1. The software clearly shows alignment between lasers and coupling components.
2. Different laser types produce distinct profiles; elliptical fitting computes major/minor axes and ellipticity.
4. 

Defect Identification

Beams closer to ideal Gaussian or flat-top profiles have fewer defects.
