An Investigation of the Photographic Characteristics of the Film UFSH-4 Used in the "Orion" Equipment
Abstract
To get the spectrograms of particular stars with the help of the orbital observatory "Orion" an adequately sensitive film of the UFSH-4 type with high resolution capacity has been used in the interval of wavelengths 4000-1800 A. The possibility of prolonged orbiting of this film in the conditions of outer space (over two months) has been proved. The sensitivity of this film has practically remained unchanged over the past period despite the heavy fogginess formed (with a density of about 0.8-0.9). No appreciable changes in the physical-¬mechanical characteristics of the emulsion layer of the above film have been discovered.
