In connection which a program of research in the physics of the atmosphere, a need has arisen for a sensitive differential photometer which would be adaptable to balloon-borne operation. This paper describes a prototype of such an instrument. The present photometer is constructed for preliminary investigations to be carried out in the laboratory, but with light weight components used in the design except for the power supply and the main structural frame. Consideration is given to these latter features to the extent that the entire equipment is designed for operation from power sources which can be directly replaced by small light-weight battery packs. The optical components are all replaceable by equivalent ones of smaller size, and the metal parts of the frame can by replaced almost entirely by fibre or plastic materials.
