“…tReinecke salt actinometry (Wegner and Adamson, 1966). narrow band radiation have been employed to determine the wavelength dependencies (action spectra) of cutaneous photoresponses in man (Magnus, 1959;Sayre et al, 1965;Knox et al, 1967;Berger, et al, 1968;Cripps and Ramsay, 1970;Mackenzie and Frain-Bell, 1973;Satoh et ul., 1974;Nakayama et al, 1974). The best of these instruments employ two dispersive elements to produce an output beam of very narrow bandwidth (5 nm or less) with low stray light.…”

Abstract— An instrument designed for convenient determination of action spectra for cutaneous photo‐responses in man and experimental animals is described. Light from 450 W Xe lamp is dispersed by a concave holographic grating. The spectrum from 244 to 616 nm is projected as a planar strip (2 times 17 cm) intercepted by a grid with 31 ports. The bandwidth at each port is 12 nm and the size of the port increases from about 4 × 4 mm to 6 × 8 mm from the low to high wavelength limits, respectively. Typical fluence rates in quanta m‐2 s‐1 are 4.0 times 1019 at 298 nm, 16 times 1019 at 394nm and 22 times 1019 at 538 nm. Responses due to delayed erythema in normal skin and to musk ambrette photoallergy and solar urticaria in patients skin have been elicited with this instrument.

Solar urticaria, an uncommon photosensitivity disorder, may be disabling for affected patients, especially those who react after short exposures to artificial or natural light. The spectrodermograph, a newly developed instrument, permits rapid, accurate determination of the action spectrum of solar urticaria. It consists of a xenon arc lamp with an emission dispersed into used to establish the wavelengths responsible for solar urticaria in 12 patients during the past four years. Knowledge of the wavelengths responsible for producing the urticarial reaction has implications for selecting appropriate therapy. The clinical course of these patients is also reviewed.
