DEFINITION
Classification: 362/803
Devices designed to give a nonactinic light for use in photographers' dark rooms.
(1) Note. Included herein are light units which include a light source which emits light which could produce a chemical change (actinic) combined with a medium which blocks or absorbs actinic radiations but passes nonactinic radiations.
(2) Note. Light sensitive material, such as photos:graphic film, may undergo a chemical change as a function of the
exposing light intensity or frequency (color). An illuminator that allows "safe" exposure of one specific light sensitive material without unwanted chemical changes may not be "safe" for a different material.
