BQM-50 ビームプロファイラ

BQM-50 は Arden 社と NPL が共同開発しましたCCD カメラタイプのレーザビームプロファイラです。

すなわち稼働部品なく、M2 を測定することが可能です。

対応波長は 400~1100nm、対応ビーム径は 0.4 ~1.5mm になります。

本製品は NPL の特許によって保護されています。


  • Complete beam characterisation - M², Divergence angle, Width at waist, Waist location, Rayleigh Range and Astigmatism etc.
  • Measurement time under 20 seconds means you can see changes in beam quality such as during warm-up
  • Wavelength range 400 to 1100nm
  • Compact size means you can measure in situ
  • Easy alignment and adjustment saves time and reduces possibility of operator errors
  • Compatible with CW and Quasi-CW Pulsed Laser source
  • USB2.0 direct connection gives portability - take the BQM-50 to where you need to do measurements.
