  1. To reduce the marking distortion, using the vertical 2 - dimension galvanometer distributing and f field lens focalize, the distance of the second galvanometer to the machining plane is the focus f. to avoid too hign temperature to distroy the resonance cavity because of too long marking time, cooling system and self - protector is used in the design

    為減少打標畸變,採用垂直二維振鏡分佈, f物鏡聚焦,將激光束經第二個振鏡反射後到加工平面的距離為焦距f ,為了避免打標時間過長,溫度過高破壞諧振腔,在設計中加上冷卻系統和自我保護裝置。
  2. Long focus object lens of three color achromatic aberration is one of two posers of optical design, using this method can get a perfect result. compared with pw method, the first results received from the wave - deviation method are more accurate and more rapid

    使用此數學模型編的光學自動設計程序,也可以說是光學鏡頭設計的一種新方法,即實現自動選玻璃,求解初始結構(曲率半徑r ,厚度d等)和自動校正像差和優化系統等。
  3. This is a long focus lens

    這是個長焦距鏡頭。
  4. Focus lens, reflect lens, yag laser whole / semi - reflect lens : they are all used import material to process, which insure the lens have long service life and low waste during the laser transmission
