Laser interferometer DON-5TSZ
Product description
Laser interferometer for determining the magnitude, sign and direction of the main axes of stress. To register the measurement of residual stresses by recording the fields of small displacements in the studied area. The method is based on the elastic load arising in the local area of the investigated product by drilling through a hole through a small diameter and depth. The accuracy of determining the strain by this method reaches ± 130 nm; these are strains caused by low residual stresses. The laser interferometry method allows you to obtain accurate data on the magnitude, sign and direction of the main stress axes in 10 ... 15 min (in contrast to the trepanation method, where the period is calculated in weeks). The interferometer consists of: • An aluminum plate 10 mm thick, on which all optical elements are installed; • The bases with three support; • The mechanism of rotation of the optical axis; • A semiconductor laser emitting light in the green part of the spectrum; • A device that creates a divergent light flux; • Dividing mirror; • Digital video cameras with a lens; • Band-pass filter; • External protective casing; • Three permanent magnets on flexible bases. The interferometer must be rigidly attached to the test surface. Therefore, its supports have sharp carbide endings, which ensure penetration into the investigated surface. The introduction of the supports into the surface occurs, first of all, due to the attractive force of permanent magnets, as well as due to the mass of the device. All optical elements - laser, video camera with lens, dividing mirror, etc. are located in one optical plane, on the plate, which can be fixed at an angle of 90 or 45 degrees to the plane of the investigated surface. The semiconductor laser of the interferometer can be equipped with a separate power supply unit from the 220V network or a set of 5V batteries. The digital camcorder is equipped with a cable with a USB connector for connecting to a computer.
