understood and met.

Principles Of Operation

Light Source

The CL Series light sources consist of an enclosure housing a high intensity lamp,
proprietary optical platform, user controls and indicators, and a power supply with control
electronics. Cooling is provided via internal fans. In the event that the fan(s) malfunctions
or if adequate air flow is blocked and/or the internal temperature of the device exceeds
the engineering specifications, an internal thermal protection mechanism will
automatically shut off power to the lamp. After cooling, the Light Sources may be
restarted.

CL Series Lamps / CL Series Replacement Lamps

The CL Series lamps are high pressure, high intensity and long life Light Sources. They
are mounted into a patented lamp fixture which is designed to allow both easy and rapid
exchange in the field as well as ensuring precise alignment to the optical platform.

Power Supply with Control Electronics

All the electricity to the Light Source is controlled through the ON/OFF switch. Power to
energize and operate the lamp, fans, and control circuitry is provided by a custom
designed, wattage regulated, switching power supply. The operational life of the lamp
and lamp life indicator are controlled by a lamp voltage monitoring circuit.
Multi Link™ Port and Multi Link™ Expansion Port
Internal, to both the Multi Link™ Port and Multi Link™ Expansion Port, are patented
coupling optics and mechanics designed to produce the highest output powers. Internal
to the Light Sources are fans and heatsinks designed to reduce temperatures at the
optical coupling joints thereby minimizing the possibility of damage to Micro Link
and fiber bundles.
Caution Do not place anything on top of the Light Source. Do not store liquid
above the Light Source.
Caution Clogged or blocked vents may cause Light Source overheating and will
result in thermal shutdown. Keep the Light Source clear of any obstructions.
Caution Fully close the attenuator before turning on the Light Source or when
operational but not in use.
