How about Zhejiang Crystal Optoelectronics Co., Ltd.? After graduating from college, I did photoelectric coating in that company. Are you tired? Is there room for development?
Zhejiang Crystal is very strong as an optical filter, and it is very good for a graduate to enter such a company. Engaged in photoelectric coating work, the early internship stage is tiring, and the later technology is no problem. After all, this is a technical job. If you want to develop space, you must look at opportunities. However, the coating industry as a whole is still ok. Engineers with about 7 years' experience are badly needed now.
