Optometry and servo are not important, it is important that the liquid lens manufacturing methods and materials.I use the PMMA board and PET film to make the lens. Fill in dimethyl silicone oil inward, change the volume of the liquid with a syringe.

The following points affect the quality of the lens

1.UV glue must be used in the pure plane bonding

2.Install the screws according to the model

3.Bonding plane can not be polished, use cnc to cut PMMA instead of laser cutting machine to prevent edge deformation

4.Use silicone oil, it does not corrode rubber, almost no bubbles
