Laser combinations would be misaligned because of many external factors e.g. lasers got fallen from height, or shocking
during transportation, long time of being used, etc.
All of these factors would cause the well aligned lasers out of shape, misaligned.
If there would be any necessary to re-do RGB alignments, there are many procedures to be completed in a high powered
RGB laser module. Because each single laser color has more than 1 only diode get combined, thus a RGB high power
module would have many permutations and combinations on alignment procedures.
Generally, if the single color are stay still(overlay itself),end users would need to do the basic alignments on RGB balance only.
Please read the steps as described herein for reference of how to make alignments on this module:
The very first step is to judge by eyes visual if the RGB(white balance) out of shape. Easy to know whether lasers are
misaligned or not from projecting a white circle, you will then see if the white balance is with slight or severe splitting.
Pictures below were taken from the 15W system and its RGB laser module.
Step 1.
Cut off all power supply
Step 2.
Open up the cover of the laser show system then access to overall internal of the system.
Laser module is set under the power supply unit, you should unscrew this power supply unit with its baseplate and put them
on the other side in the system.
Step 3.
After removing the power supply unit, we’ll see the laser module. Next is to open up the cover of the module.
Slightly remove the 8 screws fixed on the module’s cover, and will get to the internal of the core laser diodes & optics.
As mentioned above, the laser combinations would
have slight splitting only because each single color is still well aligned, so you just
need to do adjustments on the basic procedures of bringing back white balance.
Step 3-1.
That is to slightly remove the glue fixed on the RGB balance
dichro mounts #1 thru #3 and then make some slight adjustments of the 3 mounts
until achieve a good white beam(need to power on).
By powering on the laser to judge if we have obtain white balance, just be careful
not to access any electricity to yourself. WEARING insulating gloves to do all these
works is suggested.
Step 3-2.
The smaller optic mounts for each single color laser combinations are
not suggested to make any adjustments on them, especially the ones are marked
‘Fixed’ as picture view. If you had confirmed that either of the 3 different single
laser colors is out of shape too, take red laser as example, the necessary way is to
make adjustments on the smaller mounts of RM#2 and RM#3, the fixed RM#1
shouldn’t be adjusted, neither to the green and blue lasers.
Important Reminder:
To make alignments, the lasers should be kept in dry condition, so that will avoid
moisture get inside the laser module. Moist or any bad environments will impact
the lasers’ performance and service time.
