Interpreting The Results - KERR OPTILUX Manual Del Usuario

Note: To obtain an accurate measurement,
the active (light emitting) area of the curing
unit's fiber optic light guide must completely
cover the 7mm diameter radiometer
aperture. Small diameter fiber optic light
guides like the 2mm will produce intensity
readings that are much lower than actual.
The aperture is located on the front plastic
housing below the analog meter movement.
A series of molded circular steps assist in
alignment of the fiber optic light guide with
the aperture. The radiometer will accurately
measure useful curing energy (blue light -
wavelength range 400-500 nm) from 0
2 2
mW/cm to 1000 mW/cm .
To measure curing light output: Center
the tip of the fiber optic light guide (7mm or
larger) over the aperture as shown in Figure
7. Activate the light. Be sure that the tip is
positioned flush against the aperture so very
little light escapes. Read the output in
2
mW/cm , and note the reading
comparison with the next routine test.

c) INTERPRETING THE RESULTS:
2
UNDER 200 mW/cm
2
200 - 300 mW/cm
2
300 - 800 mW/cm
2
OVER 800 mW/cm
for CAUTION: Insufficient output (under
2
300 mW/cm ) can result in varying degrees
of under curing of the restorative material.
Low light output may not achieve maximum
physical properties in the light cured
material, leaving a soft uncured layer at the
bottom of the restoration.

Insufficient output:
Do not use curing
light. Inspect lamp,
filters, and fiber optic
light guide. Refer to
curing light operator's
manual and cautionary
statements below.
Increase curing time.
Use material
manufacturers
recommended curing
time.
High output: Reduce
curing time
appropriately. Refer to
curing light operator's
manual and cautionary
statements below.
