BA32-1KW

光束取样片、32 mm Ø、1000 W。

产品主要性能特征

激光功率管理

CMOS 传感器的饱和点和损伤阈值都较低。因此,控制激光功率对于获得最佳测量结果并避免损坏 BEAMAGE 相机来说非常重要。

激光光束采样

BA 系列光衰减器在两个正交光楔上采用菲涅尔反射,以去除一小部分输入光束。保留入射光束偏振状态和辐照度。

多种可能用途

  • 同时监控功率和光束剖面
  • 不具有背面反射的偏振不敏感分束器
  • 用于我们的能量或功率探测器的光学传感器
  • 针对诸如 M6 系列与 PH 系列高灵敏度探测器的衰减器

PRESERVES POLARIZATION

The BA Series Optical Attenuators use Fresnel refl ection on two optical wedges to pick off a small percentage of the input beam. Since the wedges are oriented orthogonally, the S and P polarization states are switched when the refl ected beam hits the second wedge, and the difference in refl ectance between the two states cancels out. The incoming beam polarization state and irradiance are thus preserved. The wavefront distortion is negligible and the laser output power stability is not affected.

MONITOR POWER AND PROFILE SIMULTANEOUSLY

The BA16K models include a calibrated thermal power detector that also acts as a beam dump. Simply plug the detector into a Gentec-EO Power Meter to measure and display relative power in real time.

To obtain an absolute measurement of power, you will have to determine a correction factor for the BA16K. This can be accomplished in few simple steps. Note, however, that such a correction factor is dependent on the laser polarization and will only be valid if the polarization is stable over time.

In the near future, a power measurement feature will be added to the PC-Beamage software which will then be able to display the laser power density.

MODULAR CONCEPT

The “Sampled beam” port can be connected to the Beamage via the included adaptor tube. The adaptor tube is also compatible with our ND fi lters for additional attenuation (recommended for small beams at high power). An ND4 fi lter is always included with the purchase of a Beamage profi ling camera.

The BA Series Optical Attenuators can also be used, stand-alone, as follows:

  • OPTICAL PICK-OFF FOR USE WITH OUR ENERGY OR POWER DETECTORS
  • ATTENUATOR FOR OUR HIGH SENSITIVITY DETECTORS LIKE M6, PH, ETC.
  • POLARIZATION INSENSITIVE BEAM-SPLITTER WITH NO BACK REFLECTIONS
