Ophthalmic Lens Coating Machine OSA-90T

The box-type ophthalmic lens coating system is designed to provide AR-Coating on ophthalmic lenses. The unit can be installed in clean, dry rooms of vacuum labs or vacuum coating workshops.

Technical Data
Basic System Configuration
Pumping system
Turbo Molecular pump T-1600(LEYBOLD), Rotary vane pump model E2M80 (Edwards Highvacuum,UK), Cyropump for water vapour pumping model VTC CRYO-6.
 
Evaporation Source
TELEMARK (USA) Electron Beam Evaporator with 6-Pocket crucible.
A beam pattern controller is used for optimization the evaporation.
 
Substrate Heating system
The Heating system incorporates two infrared heaters, a thyristor unit and PID controller.
The system provides heating to max, temperatures of 150°C.
3-kW infrared heater with auto temperature control provides uniform substrate heating over the dome.
 
Control System : Fully automatic PC system
