High Energy Focused Beam Profiler
•Datasheet: High Energy Focused Beam Profiler
The Photon High Energy Focused Beam Profiler allows for accurate profile measurements of high energy focused laser beams with dimension down to ~10µm (5µm*). A requirement for 2-3% accurate measurement of TEM00 beams using camera profilers is that the beams expose a minimum 8 pixel-wide area. Use of magnification meets this requirement for beams with dimension <50µm and for typical profiling cameras with pixel dimension in the range from 4-7 µm. Additionally, the High Energy Focused Beam Profiler provides proper attenuation of the beam, up to over 12 orders-of-magnitude, using a combination of laser-grade front surface reflectors, interference filters, and fixed and variable absorbing glass filters. This allows for measurement of high power beams at over 100W. The Model FSP-2512 comes standard with the Photon FireWire BeamPro 2512 operating with Photon's BeamPro Acquisition and Analysis Software.
The Model FSP-2512 system includes a C-mount imaging spherical AR-coated singlet lens. This attaches to a pair of polarization-preserving quartz prisms providing front surface reflection attenuation of ~0.0005 (~OD3.3) at 532nm. These mount to the Photon ATP-K with continuously variable attenuation of OD1.7 to OD4.6 with an additional fixed OD2.8 attenuator between the prisms and the ATP-K. This configuration reduces a 10W beam to the pW levels required for the camera sensor. Additional attenuation can be provided after the prism pair using interference filters to measure beams with higher powers. Standard systems provide nominal magnifications of 5X, 10X, and 20X. Other magnifications, broadband and dual wavelength AR coatings, and cylindrical lenses are also available.
The measurement is made by relaying the image of the focused spot to the camera array. High energy/power measurement is possible because the spot is not focused on the lens, but rather the lens is carefully positioned so that the focused spot is at the working distance of the lens, generally 5 to 10mm from the lens.
