"People don't care how much you know
until they know how much you care."
What we do:
Our technology is based on years of researches and experiments. Main problem we experienced is lack of original parts because they have been discontinued about 5 years ago. We tried many items and brands, manufacturers and suppliers, methodics and markets... Finally we have stock of ORIGINAL LASER DIODES to be used in all Types of Noritsu lasers. We have developed a number of solutions for every of major problem, up to producing our own custom-made laser guns, semiconductor Blue (450 nm) and SHG Green (532 nm).
We accept for repair only complete customer laser units but sometime it's still hard to repair them with existing methods and we are getting involved to new fascinating researches and experiments. Hundreds of Laser units were already repaired and some of them were the real victory of engineering mind and could be done exclusively because of patience and trust of some of our dear customers.
We do not have a wet minilabs, our laboratory is fully equiped by the test equipment, jigs and test beds to let us check every function of Laser unit. We are able to confirm working condition without testing on the minilab. We give warranty 6 months, but restored units basically operate much longer. Of course we have a few percent's failure rate, and returned units are the best material to learn what went wrong through our total control and keep us motivated to improve continuously our technology.
There are a dozens of scenarios, what we do with particular laser units. However the standard Laser Unit servicing consists of the following steps:
- External overview. Repair of slight damages, such as wires and connectors if any
- Internal overview. Checking positions and angles of mirrors. Inhaling of screws
- Diagnostics
- EEPROM Checking and Analyzing (For Types A, A1 and FF only)
- Blue gun refurbishment
- Blue gun parameters recalibration
- Laser Driver PCB modification (For Types A1 and FF only)
- AUTOTUNING procedure (For Types A, A1 and FF only)
- Testing program for renewed Blue gun. On-off cycles, warm-up/cool-down cycles, checking for stability
- EEPROM Reprogramming (For Types A, A1 and FF only)
- Chasing for Optical Noise
- Green gun recalibration
- Red gun readjustment
- AOM output inspection. Checking signal paths. Restoring the form of the beams
- AOM crystals re-positioning
- Clean Optics
- Mechanical alignment of the optics
- Inspection of each beam output in front of exit glass. Adjusting factory presets if necessary
- Polygon mirror inspection
- Synchrosensors mechanical checking/adjustment
- Beam Focusing (sharpening)
- Convergence checking/adjustment
- All three beams ON together and test them with polygon rotation and reading of synchrosignals
- Power-on at different output levels - Minimum, Normal, Maximum
- Measure and record all the data for further reference and statistics
- Next day cool start and full test anew
- Clean up and blow out the internal layout. Close cover
Now you have to understand why we do not accept for repair the separate laser guns. In 70% of cases the repaired gun is insufficient and entire device will not work properly and reliably. We are proud to offer our customers the last and improved solution to get back in to the stable business. The final stage, the running of newborn Blue before the unit will be shipped out is showed on the picture below:
