Analysis on the repair method of surface shape accuracy in the processing of UV optical lenses

Factors affecting the surface shape of optical lenses;
1. If the surface of the grinding tool is higher, the lens is lower. Instead, it is higher.
2. If the thimble is put out, the face shape will become lower, otherwise, the face shape will become higher.
3. The swing mainly ensures the wear area of ​​the lens, so that the overall change of the surface is small.
4. When the angle is large, the surface shape is easy to become smaller, otherwise, it becomes larger (but with the change of other parameters, it will be different). So it depends on the operator's experience.

UV transparent optical lenses play a very important role in lens applications. Lenses must be pre-cleaned prior to coating. Cleaning requirements are high, down to the molecular level. Various cleaning liquids are placed in the cleaning tank, and ultrasonic waves are used to enhance the cleaning effect. After cleaning the lens, place it in a vacuum chamber. During this process, special attention should be paid to avoid dust and garbage in the air from adhering to the lens surface. The cleaning after Z is carried out in a vacuum chamber. During this process, special attention should be paid to prevent dust and garbage in the air from adhering to the lens surface. Post-Z cleaning is performed before electroplating in the vacuum chamber. An ion gun placed in a vacuum chamber will bombard the lens surface (eg argon ions). After this cleaning process is completed, an anti-reflection coating is applied.

Factors affecting the surface;
1. The surface of the abrasive is not good and needs to be repaired.
2. The concentration of the finely ground coolant is low or the use time is too long, and there are too many glass fragments mixed.
3. The size of the ground glass is not good.
4. The tablet is damaged or leaked.

Repair method of optical lens mold;
If the lens surface is high, if the grinder is on top, then the pendulum is small, if the grinder is below, then the large pendulum. If the lens surface is lower and the grinding tool is at the top, the large pendulum and the grinding tool are at the bottom, the small pendulum.
