Abstract
The x‐ray small‐angle camera consists of two glass blocks. One of them is used as a monochromator by total reflection, the other shields the plane of observation from background radiation. In connection with a microfocus x‐ray tube, this camera offers high intensity and large resolving power. The primary beam is limited only by the width of the microfocus and by the slit between the glass blocks. A comparison has been made with the intensity scattered by a Lupolen sample recorded by a Kratky camera with a quartz monochromator and by our camera. If both cameras are adjusted to the same resolving power (1000 Å), the parasitic scattering is the same for both cameras and the intensity of the glass camera is 4.2 times larger.
