NEW: IMPROVED DESIGN
It is now even simpler to install a BA beam sampler into your optical system. The input and output sides on all BA16 models now include an SM1-threaded aperture and four M4-threaded holes compatible with 30-mm cage systems.
MANAGE THE LASER POWER
CMOS sensors have low saturation levels as well as low damage thresholds. It is thus very important that you control your laser power to get the best measurement possible and avoid damaging the BEAMAGE camera.
Sample your laser beam
The BA series optical attenuators use Fresnel reflection on two orthogonal wedges to pick off a small fraction of the input beam. The incoming beam polarization state and irradiance are preserved.
Many possible uses
- Monitor power and beam profile simultaneously
- Polarization insensitive beam-splitter with no back-reflections
- Optical pick-off for use with our energy or power detectors
- Attenuator for our high sensitivity detectors like M6 series and PH series

The BA series optical attenuators use Fresnel reflection 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 reflectance 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/BA32K 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/BA32K. 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.
The “sampled beam” port can be connected to the Beamage via the included adaptor tube. The adaptor tube is also compatible with our ND filters for additional attenuation (recommended for small beams at high power). An ND4 filter is always included with the purchase of a Beamage profiling 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
