Investigation of the erythema effectiveness curve with tunable lasers
Abstract:
The erythema effectiveness curve (EEC) has been remeasured with frequency-doubled tunable dye lasers in the wavelength range from 250 to 320 nm. The EEC has been determined from the response of the skin of adult white males after application of a 5 mJ/cm2 radiant exposure. Additionally, minimal erythema doses have been measured. The results confirm earlier observations but give curves with a smaller half bandwidth. In the range from 290 to 310 nm, the EEC has been measured after application of 8-methoxypsoralen and of 3-carbethoxypsoralen.
