The automated ultrasonic cleaning takes an important part in the preparation of the anti-reflective coating. Only perfectly cleaned lenses can be processed.
All lenses mounted onto special fittings pass through the fully automated cleaning stages. Each cleaning basin contains different detergents or so-called purified water.
The entire cleaning process is supported by ultrasonic. The lenses are dried after the ultrasonic cleaning process.
Special intensive filters guarantee the continuous supply of purified water to the automated washing system. The purity of the water is controlled continuously as the smallest impurity in the basins might incur a defect in the anti-reflection coating.
