We commenced a series of partial and later whole-lesion treatments with a 532 nm KTP laser (3 and 4 mm spot sizes, radiant exposures 12 to 28 J/[cm.
For the installation in Arizona, the ASTM G90 standard was used as a guideline with an important modification to calculate radiant exposure at the UAWS target plane.
The instantaneous irradiance multiplied by time duration of exposure results in the radiant exposure of the exposed specimens in the 295 to 385 nm spectral region expressed in MJ/[m.
Using these concepts, it is possible to calculate expected radiant exposure using the UAWS as well as compare radiant exposure rate using the UAWS with unaccelerated and moderately accelerated exposure methods.
Dividing the potential average yearly UV-radiant exposure using the ultra-accelerated device by the historical average yearly UV-radiant exposure on 45[degrees] south in southern Florida (17000/275), results in a radiant exposure acceleration factor of approximately 63 (approximately 56 for 5[degrees] South Florida).
The radiant exposure (defined as irradiance x time) of each LCU in the area of the spectrum below 470 nm was 17.
This is probably because the radiant exposure values in the 450-490 nm range, which is the area of major absorption by CQ, (25,26) was very similar among the LCUs tested (20.

Exposures at 45[degrees] in Arizona accumulated total solar radiant exposure (dose) slightly faster than at the 5[degrees] exposure angle.
Additionally, a much more diffuse sky dome in southern Florida (compared to Arizona) may help average direct and diffuse total solar radiant exposure, as shown in Figure 3.
Exposures at 5[degrees] in Arizona accumulated UV (ultraviolet) radiant exposure (dose) faster than at the 45[degrees] exposure angle in Arizona.
The significant differences in radiant exposure due to different exposure angles did not appear to cause significant effects in this experiment since exposure angle did not show a significant effect on the results.
