Problems solved by technology

Due to the large volume and large heat capacity of optical glass, traditional electric soldering irons cannot be used for soldering. Therefore, the measurement of resistance prepared on optical glass becomes very difficult. It can only be theoretically estimated through the process of resistance preparation, making the optical system The yield is very low and the cost is very high
