The 650 nm laser beam light of phone jammer is the redder type

 cell phone jammer can be commissioned and adjusted for the customer.
Surface quality; The use of aluminum and aluminum alloy matrix materials (1) general; (2) high-speed, stainless steel or ferroalloy; (3) Special low speed when the selection of quartz, borosilicate glass and machinable ceramic. Physical properties. Matrix material selection; Operating speed; Operating temperature; Work and storage temperature range. 13 Huazhong University of Science and Technology the Wenhua graduation design (thesis) of all the allowed values by the image quality to determine, for example: 16-surface multi-row reflector laser simulation with the indexing of its surface errors as well as the face of the tilt tolerance of the shaft 2 "or less, the face of the center axis deviation of 0.003mm flatness λ/10 below. The 650 nm laser beam light of phone jammer is the redder type.
In Figure 4-1, the laser emits the laser beam, after the auxiliary lens, reflector convergence in scanning polyhedra, each polyhedron is a mirror. Each turned to a surface, the beam scanning time, if the polyhedron with N faces, then the synchronous motor of a turn each beam scanning N, measured at the beginning of light along the oabo 'route through the lens 6 and 8 to the photoelectric receiver 9 on. 15 Huazhong University of Science and Technology the Wenhua graduation design (thesis) polyhedron rotates clockwise, the scanning beam will move down, and finally along o a'b'o 'to leave the lens. The reflection point of the polyhedron O and phototube O 'are located in the focus of two lenses. The 635nm laser beam light of cell phone jammer is more like the pink type.
Between the two lens beam is parallel to the system optical axis parallel to the beam. No workpiece is placed in the optical path during the scan light from ab to a 'b' are put into the photocell, the photocell output. When the polyhedron continues to rotate the beam to leave the lens, no light on the phototube, the output is zero. Then the second reflecting surface of the polyhedron and repeat the process of a reflective surface. Figure 4-2 is the waveform of the output of the phototube. When the workpiece is not placed in the scan area, the output signal of the phototube Al shown in Fig. Into the workpiece, the phototube signal beam scanning device under test is reduced to zero, as shown in shown in A2. It is the preheating time of cell phone jammer .
