Feature: ETL-50DP adopts the most advanced international technology, uses the semiconductor light emitting diode pump ND; YAG medium, with the wavelength of 808nm. Causes the medium to produce the massive reverses granule, forms the wave length in under the Q switch function is the 1064nm great pulse laser output, the electric light transfer efficiency is high. The volume of this kind of laser is small, which is 1/4 of traditional DP laser machine. DP semiconductor laser marking machine has the most advanced laser technology and adopted import semiconductor array the pump source. With wave length 808nm semiconductor light emitting diode pump ND: YAG medium. It volume is small. The volume is only the one fourth of the traditional DP laser marking machine. Its optical system uses the entire seal structure and has the path of rays to look at in advance with the focal point instruction function. It has a beautiful appearance and the operation system is more convenient. This machine provides new outside water-cooling system. The movement noise is extremely low; its precision of temperature adjustment is very high. It has provided the most reliable safeguard. Laser, power source, the work platform uses the integration structural design. The efficiency of marking is high and marking metal is better. Application: May marking the metal and many kinds of nonmetallic, applies in processing situation which requests is high precision and depth. And widely applies in the following industry such as the electron component, the integrated circuit (IC), electrician electric appliance, handset communication, hardware product, tool fitting, precision instrument, eyeglasses clock and watch, jewelry product, automobile fitting, building materials, food and drugs packing, PVC tubing, medical instrument.
