Beam Propagation analyzer: M2 / 光束傳播分析: M2

M²-200S
* Automatically measure your beam quality in under 2 minutes
* Tune your laser for best operation
* ISO compliant
* Specifically developed for continuous usage
* Unequaled accuracy using patented UltracalTM
* calibration
* Automatic attenuation adjustment
* Pulsed and CW for most beam diameters and powers
* Compact and portable

Not all commercial M² measuring instruments conform to the ISO 1146 method of employing
a fixed position lens and moving detector. Instead, some manufacturers use a fixed position
detector and a moving lens. If the laser beam is diverging or converging within the travel range of
a moving lens, the reported M²  value and other results can be significantly compromised.
Spiricon’s M² -200s and M² -200 Beam Propagation Analyzers are fully ISO 1146 compliant.

AUTOMATIC M² - AT PRODUCTION SPEEDS
The M²-200s optical train uses a fixed position lens and camera. The mirrors that direct the
focused beam into the camera are moved to precise locations, translating the beam through both
the waist region and the far field regions. All these measurements and translations, as well as
incremental beam attenuation, are automatically controlled by the M² -200s software.
Software improvements in the M²-200s,including more efficient algorithm execution, has

decreased  the measurement reporting time by 2-3 times, making it possible to report  M² in
under two minutes.

M² -200S
* 2分鐘內自動量測光束特性
* 將您的雷射調製最佳操作
* ISO 驗證
* 設計為可連續使用
* 具專利保護的 UltracalTM產生不平均的準確度
* 計算
* 自動衰減的調整
* 脈衝和連續光的光束直徑和功率
* 輕巧可攜帶

並非所有商用的 M² 量測儀器都遵守 ISO 1146 定點透鏡和偵測器移動的方式.
有些製造商使用定點偵測器和移動透鏡的方式. 若在透鏡移動行程中, 雷射光束聚焦或發散, 則 M² 值和其他量測結果會受影響. Spiricon的 M²-200s 和 M²-200 光束傳播分析儀是遵守 ISO 1146 規範的.

自動 M² - 生產線適用
M² -200s 儀器使用固定透鏡和偵測器的方式. 精準位置的鏡面將聚焦光束打到CCD上, 將光束光腰和遠場位置移動. 這些量測和移動, 以及光束傳播的衰減, 由 M² -200s 軟體做自動控制. M² -200s的軟體改進,包含執行運算法則, 將量測時間縮短 2-3倍, 讓 M² 量測可以在2分鐘內完成.
