Warning, read the manual before operating the unit.
Possibly hazardous optical radiation emitted from this product. Do not stare at operating
lamp. May be harmful to the eyes.
Caution, hot surface
Direct current
Light-absorbing materialshave the physical property of converting incident light into heat. Damage may occur to heat
sensitive or flammable light absorbing materials. To avoid such thermal damage and the potential danger of fire or
burns, please adhere to the following instructions:
Never block the optical output aperture or place any part of the body in the light output path.
Due to the high optical power in the focal area only fiber optic light guide with glass optical fibers should be
used. Plastic optical fibers may be damaged due to the high temperatures.
Do not cover any of the air vents when operating the unit.
Use only the included power supply adaptor.
Disconnect the power cord when the unit will be left unused for long periods of time.

Operation
1. Place the MC-LS on a sturdy, flat surface. Ensure there is at least 2” of space between the top, rear, and
sides of the unit and other equipment.
2. Insert the fiber optic into the nosecone. Gently tighten the thumbscrew by hand to secure the fiber optic.
Over-tightening the thumbscrew may cause damage to both the MC-LS and the fiber optic.
3. Insert the power supply plug into the DC power receptacle on the rear of the MC-LS.
4. Plug the included AC power cord into the power supply and a grounded receptacle with the appropriate
voltage and frequency.
5. Press the pushbutton on the front panel of the unit to turn it on. A blue light on the pushbutton will illuminate
to indicate that the LED output is enabled.
6. Rotate the knob on the front panel to control the LED intensity.

Remote Operation
Basic use of the remote operation features are
described in this section. Cable lengths must be
limited to a maximum length of 3m.
Analog/Digital Controls
The MC-LS may be operated remotely using a
potentiometer and a switch connected to the
appropriate pins of the IN/OUT port as shown in
Figure 3.
In the default configuration, the MC-LS must first be
turned on using the front panel power switch.
Connecting Pin 1 (Digital Input) to Pin 5 (Common)
will then turn off the LED output.
Serial Control (USB or RS-232)
The MC-LS may be controlled remotely using
simple text commands sent over the USB COM
port or RS-232 serial port. The RS-232 port must
be configured for 9600 baud, 8 data bits, 1 stop bit,
and no parity.
All commands begin with an ampersand (&) and
end with Carriage Return, ASCII code 0x0D
(typically denoted as ‘\r’).
Basic operating commands:
Please refer to the MC-LS product page of the SCHOTT website for further information about remote operation.
