5.7 Use Point Cure Lens: The magnetic Point Cure Lens provides pinpoint
curing of small composites and is helpful for tack curing veneers and all
porcelain crowns.
For veneers, the Turbo mode with a 1-second curing time allows for point
curing the center of a veneer with the ability to then clean up the uncured excess
around the margins, then cure the entire restoration using the full-sized curing
lens.
For all porcelain crowns, place the curing light on the buccal and lingual
surfaces and point cure using Turbo mode for approximately 2 seconds each,
clean up the uncured resin around the margins, then cure the entire restoration
using the full sized lens.
5.8 Caries detection using Check mode
Select the Check mode, when purple light irradiates caries or dental plaque,
it will produce orange red fluorescence reaction to detect surface caries or dental
plaque.
WARNING: Check mode is prohibited for curing resin-based materials.
5.9 Measuring the light intensity
The integrated radiometer allows the light intensity (mW/cm2) to be measured
easily and quickly while the charging base is connected.
To measure the light intensity, place the tip of the top of main unit, without

8
disposable sleeve, flush into the marked recess on the upper side of the charging
base. Then activate the light and read the value displayed on the screen.
Measurement accuracy is in the range of +/–10%.
CAUTION: If the tip of the top of main unit is placed obliquely to measure
the light intensity, there will be obvious deviation in the measured light intensity
value. The effective measurement of the integrated radiometer is the diameter of
the light source is 10 mm, if the measured light source diameter is not 10 mm
(As common 8mm), it will lead to the obvious difference in the measured light
intensity. At the same time, different manufacturers have different standards for
measuring the light intensity value. It is suggested that it should only be used
for measuring the original curing light. If it is not the original curing light, the
measured light intensity value may have obvious differences.
