Laser pointer that can be used for measurement
A laser pointer includes a pen body, a pen tip fixedly connected to one end of the pen body, a laser generator housed in the pen tip, a power switch for controlling the laser generator, and a measuring device. The measuring device includes a tick A dial and a measuring disk; the dial can be relatively rotatably connected to the pen body and accommodated in the pen tip; the peripheral wall of the dial is provided with a scale area corresponding to the size of the product defect, and the peripheral wall of the dial Exposure to the tip of the pen; the measuring disc is provided with a plurality of circular holes corresponding to the scale area of ​​the scale to transmit the laser beam generated by the green laser pointer generator; the measuring disc is fixedly connected to the scale through the rotating scale The size of the circular hole of the measuring disk located on the optical path of the laser generator can be adjusted to control the size of the light spot generated by the laser pointer.

Light Source
The brightness of a laser source is a measure of its output power and beam quality. Essentially, it is the high power laser pointer power divided by the BPP. Therefore, its unit is W/cm2, and for clarity, the laser diode is at the edge emitter. Other common laser types, including vertical cavity surface emitting lasers (VCSEL), strip/stack, array or quantum cascade lasers (QCL), are not in our discussion due to their obvious deviations. However, similar methods can be used to evaluate each series to narrow the scope of application. Laser surface denaturation is the use of high-power lasers and material properties to change the surface properties of components. If necessary, give the laser surface resistance to friction (normal temperature or high temperature), fatigue resistance, and corrosion resistance. Due to the identification of the metallurgical industry, we have developed laser nano-ceramic alloying, laser denaturation enhancement technology (laser quenching), laser melting and covering repair technology.
