4.) Switch on the polymerization light. The Bluephase Meter II is
activated automatically. The previously set diameter is
displayed, providing visual feedback.
5.) The measurement result of the light intensity is displayed in
milliwatt per square centimetre [mW/cm²]. Note: If the light
intensity is below 300 mW/cm², "MIN" is shown in the display.
6.) Turn off the polymerization light. The Bluephase Meter II turns
off automatically.
Measuring the light power (radiant flux) in [mW]
1.)
2.)
To convert [mW] to [mW/cm²], the measured light intensity must be
divided by the active light emission surface [cm
Example: 670 mW divided by 0.608 cm
Acoustic signal
If any button is pressed, an acoustic signal sounds. By pressing the
(+) and (–) buttons simultaneously and for a longer period, the signal
tone can be activated or deactivated.
What if ...
– ... the measurement results correspond with the data
provided by the manufacturer?
The polymerization light achieves the stipulated light intensity
and can therefore be used according to the polymerization
recommendations of the respective manufacturer or stipulations
of the corresponding composite manufacturer.
– ... the Bluephase Meter II shows a value below 500 mW/cm
500 mW/cm
polymerization lights. If the light intensity is lower, it cannot be
ensured that the composite material is completely polymerized.
Therefore, it is recommended to replace a curing light with a
light intensity of less than 500 mW/cm
is the absolute minimum of light intensity for
