What are the processing temperature requirements and glue requirements for optical lenses?

Due to the high precision of optical processing and special processing objects, it must be carried out in a dedicated optical workshop. Therefore, in addition to the general machining rules, the unique safe operation requirements of optical processing must also be observed. The editor below wants to share with you the content about the processing temperature requirements of optical lenses and the rigid requirements for glue. Welcome to read!

Processing temperature requirements for optical lenses:

Since the chemical effects during polishing intensify with increasing temperature, the effect of temperature on polishing efficiency and quality will increase polishing efficiency. However, since the polishing mold mold glue and adhesive used in the classical process are mainly made of rosin and asphalt in a certain proportion, a certain proportion is only used at a certain temperature. In addition, they are sensitive to temperature changes. If the temperature is too low, the consistency of the polishing mold and the part will be poor; if the temperature is too high, the polishing working surface of the polishing mold will be deformed. These two will make it difficult to guarantee the accuracy of the machined parts, especially the aperture is difficult to control and modify. Practice has concluded that the temperature of the polishing chamber should generally be controlled at 22 °C ± 2 °C.

The fluctuation of the temperature required to check the room temperature directly affects the inspection accuracy. On the one hand, because precision optical instruments are very sensitive to temperature fluctuations; on the other hand, when the measured part is not constant temperature, the temperature difference between the inspection tool and the part will directly affect the reading accuracy. Therefore, the laboratory must be kept at a constant temperature and controlled within the range of 22°C ± 2°C.

What are the rigid requirements for the glue of optical lenses?

• UV glue has high optical transparency, and the light transmittance after curing can reach more than 90%;
• Good adhesion, anti-yellowing and anti-aging properties;
• Solvent and moisture sensitive materials can be used;
• Control curing, adjust waiting time, adjust curing degree;
• Second-speed curing, suitable for automated production lines, effectively improve production efficiency;
• UV glue needs to be solvent-free, VOC-free, safe and environmentally friendly.
