Photon manufactures a full spectrum of Beam Profiling instruments for pulsed and CW sources using scanning slits, pinholes, CCD arrays, goniometric and knife-edge technologies.

Photon instruments measure both near and far-field irradiance distribution patterns of lasers, laser diodes, LEDs, VCSELs and optical fibres.
Products available include:
ModeScan Measures both CW and kHz pulsed lasers with the NanoScan head covering the entire wavelength range from UV to FIR.

• A 200mm and 400mm lenses are available to generate the proper artificial waist for the laser source under test.
• For ease of alignment, there is an entrance iris on the optical axis of the ModeScan for ease of alignment
• A precision alignment stage for horizontal and vertical positioning
• This instrument is specifically to make automated M-squared measurements

High Power NanoScan:- Newest high power BeamScan with highest dynamic range in scanning slit technology, providing sub-micron accuracy for beam size and position.

• Equipped with a pyroelectric detector, copper slits, drum and a cooling fan
• Can measure focused laser beams up to 5 kilowatt for CO2 lasers at 10.6μm, 1-2kW for ND:YAG lasers at 1064nm other shorter wavelength lasers to somewhat lower powers in the hundreds of watts.
• Ideal for measuring lasers operating with pulse width modulation power control.

High Precision NanoScan: Photon's NanoScan scanning slit profilers provide major performance enhancements while maintaining the ease-of-use and flexibility that customers have come to expect with the world-renowned BeamScan profiler.

• Measures CW and pulsed beams across the entire spectral range from UV to far infrared, and with laser powers up to the kilowatt level
• Has an all-new digital controller based on the PCI architecture which provides deep, 12-bit digitization of the signal for enhanced dynamic range up to 35dB optical (70dB electronic).
• The software-controllable incremental scan speed (1.25-20Hz) increases the dynamic range, which allows for a much greater operating space for a single scan head.
• The digital controller has improved the accuracy and stability of the beam profile measurement & it is now possible to measure beam size and beam pointing with a 3-sigma accuracy of several hundred nanometers
