Bright, Visible Light
The bright, visible light energy emitted by curing systems can cause eyestrain if proper eye protection or
shielding is not used. Tinted eye protection and/or opaque/tinted shielding can be utilized to address this
concern.

UV-light source
s can be more “worker friendly” than many commonly accepted industrial processes, provided
the potential concerns are addressed. Both the lower working temperature and lack of spurious frequency
transmission that this system produces make it even more user friendly. Contact your Dymax representative

Product Overview
Description of the
BlueWave 75
The
BlueWave 75
is a high-intensity, UV light-curing spot lamp used for the curing of adhesives, coatings, and
potting materials. It emits UV light from a lightguide which can be hand-held for complete mobility, fixtured
into position for repetitive operations, or integrated into automated equipment.
The unit consists of an anodized aluminum housing, containing an electronic power supply, circuit protection,
a bulb/reflector assembly, an internal light filter, a thermostatically-controlled cooling fan, a lightguide mount,
bulb and unit status indicator lights, a combination resettable and non-resettable hour-meter, and a shutter
system. A thermal shutdown sensor is provided for internal temperature control of the unit. A cover-closed
switch and lightguide-sensing switch add to the safety of the unit. Fan filters should be changed or cleaned
frequently to prevent blockage and reduced ventilation airflow. Electric shutters are supplied with timed and
manual shutter operating modes. The lightguide is separate and plugs into the lightguide entrance fitting on
the front panel (the forward facing lightguide mount).
An intensity control feature allows operators to adjust output intensity during process validation and
production. Users can now manually adjust intensity to compensate for bulb degradation and to maintain an
optimized output or allow it to emit direct line of sight energy to unprotected personnel.
CAUTION:
Once the lightguide is engaged there exists the possibility of light emitting if the unit is
triggered. Never look directly into the lightguide.
A cooling fan is provided to keep the bulb housing and internal components of the power supply at the
optimum operating temperature. The fan or exhaust opening must not have any restriction in their airflow
path. The UV source is a 75-Watt short-arc bulb mounted in a reflector and pre-focused to provide optimum
light output. The unit is rated for continuous operation.
The blue indicator light (located above the lightguide mount) lights when the bulb is operating. The power
supply operates on line voltages between 100 and 240 VAC and frequency between 50 and 60 Hz.
If the bulb extinguishes due to a momentary power failure the unit must be turned off and allowed to cool 20
minutes before attempting to re-ignite the bulb. Arc-type bulbs are designed to (and prefer) to be run
continuous. Repeated on/off cycling decreases bulb life and accelerates intensity degradation. It is good
