Balanced filter method of X-ray diffraction measurements developed by P. A. Rosshas been applied to photographing Debye-Scherrer diffraction patterns. Balanced filters of Ni and. CO are used for Cu Ka radiation. In this camera one side of the photographic film is exposed to filtered radiation by Ni foil and the other side to filtered radiation by Co foil. The construction of the camera and the photographs and microphotometer curves of several diffraction patterns obtained with it are reproduced.
It is also shown that the camera may be employed successfully for the identification of crystals, because two patterns of the samples to be compared may be photographed side, by side on a film, samples being replaceable accurately to the same position by a device of the specimen holder.
