Technics of Midget laser projectors
All Midget projectors are developed, tested and manufactured in Germany by MediaLas. Each
projector and its components run through extensive tests and alignment procedures, to ensure
a long and stable lifetime. The sandwich heat exchanger not only increases stability, but also
reduces thermal effects on the lasers and optics dramatically.
Due to the nature of high-tech optical equipment used in the optical table section of the
Midgets, the devices are more sensitive to external influences than normal lighting devices.
Please use this manual for basic hints and tricks for maintenance of Midget Laser Systems. In
case of any further help, please contact our service staff. Actual phone numbers and contact
information is provided on our website at www.medialas.com
Specification of laser output power
All Midget laser systems´ output power is specified "after the laser", as stated in brochures
and websites. The laser output power can be measured inside the housing, after beam
combination and collimation BEFORE the scanner mirrors and output window.
Adjusting the scanners
On normal circumstances and under normal operating conditions, there is no need to readjust
the scanners. If, for any case, a readjustment has to be done, please refer to the separate
manual "Scanner tuning/MicroAmp drivers".
Aligning the optical color mixing device
After heavy transportation, or after large temperature differences, coming from outside cold
ambient to an inside warm ambient, it might be necessary to realign the optical setup inside.
Under normal circumstances, the optical section is maintenance free, and does not need to be
realigned.
The Midget optical section was designed for very easy alignment. The front panel can be
easily removed by the user, to adjust RGB mixing very easily from the front.
