Abstract
The utility model provides an optical shutter filter adjusting unit, relates to the technical field of X-ray diffractometers, and solves the problem that in the prior art, a filter carrier is physically added or removed to realize opening and closing of the filter carrier, so that an optical path is changed. The optical path needs to be recalibrated after each time of adjustment, and the precision of final experimental data is easily affected. The device is characterized in that an optical shutter filter adjusting unit comprises an optical shutter which is opened and closed so as to allow X-rays to pass within a specific time interval; one end of the through hole is a light inlet hole, and the other end of the through hole is a light outlet hole; the filter is mounted on the optical shutter and is used for filtering the X-rays at the light outlet or the light inlet of the optical shutter so as to select the wavelength or reduce the light beam intensity; the lantern ring is rotationally installed on the optical shutter and does not block the X-ray light source to penetrate through the through hole, and the filter piece is fixedly installed on the lantern ring, so that whether the wavelength of the X-rays passing through the through hole is selected or the light beam intensity is reduced or not is adjusted through rotation of the lantern ring.
