Non–Uniformity Ratio: 6:1
Maximum Effective
Intensity Ratio: 2:1
Spatial Pattern: The applicator produces a collimated (cylindrical) beam with
an area of 1, 5 or 10 cm², measured 5 mm from the ceramic
disc surface when the radiation is emitted into the equivalent
of an infinite medium of distilled water at 30° C.
The beam of the applicator is circular in all planes parallel to
