Optical Lens Coating Machine



Optical lens coating is one of the major application of the vacuum chamber coating machine. Goldstone use worldwide advanced technology and high quality components to provide you the customizing and flexible total solutions.
We have supplied optical coating systems to many Chinese military companies and researching institute, the machine is well-know in the field.
The machine is applied on optical film and electric film coating process, the glass, polymer, plastic and ceramic could be the available substrate for coating.
With the diffirent components and module, the machine can produce various products like accuracy optical lens, glasses lens, IR filter, AR coating, wide band filter, cold reflector, ITO conductive film, CPL lens, VCD film and laser film, etc.
     
We can make the customizing machine also to match different requirement.
Chambers
The chamber is made of stainless steel, the structure has been optimized for best allocation of components and convenice for opertation, and the state-of-the-art manufacturing guarantee the pefect welding and vacuum sealing.

The pumping system sits on the back which makes the machine convenient to maintain, disassemble and clean. The outside of the chamber is covered with cooling pipes. Standards chamber size is 550, 700, 900, 1100, 1300, 1500 and 1800mm.
Pumps
High efficient vacuum pump system guarantee the cycle time at any ultimate conditions on the coating machine. Chinese famous pump or Germany Leybold, USA Varian products could be selected for this machine. The system is composed of high-performance oil diffusion pump, Roots pump and rotary pumps.
You can select turbo pump, dry pump and cryopump as well for hyper vacuum applications.
The system can provide a short pump down time less than 15 minutes from atmosphere to 5 X10-3 Pa. The freon trap is reserved and mounted on the outlet of the diffusion pump.If the coating substract is made of polymer materials, then Polycold deep chilling system is suggested to be equipped and guarantee the vacuum pumping speed and vacuum degree.
Polycold system
For plastic lens coating, suggest use the Polycold system to reduce the vacuum pumping time as well increase vacuum degree. You can choice Chinese products and we will reserve the interface to installing of other foreigner products.
Electric Beam Evaporation

One or two electron beam evaporator(s) is installed depending on customer's requirement.



The beam evaporator includes a high voltage power supply, an electric gun and the water-cooling crucible with cavities. The crucible could rotate either clockwise or anti-clockwise. The rotary speed is adjusted from 0.2 to 2 rpm. In our high-class machine, the magnetic seal is adopted for crucible movement. The deflection of electron beam is 270 degree.



The evaporator capacity is rated from 6 KW to 15 KW, can match your different requirement for material evaporation.

The beam can scan the material in round, square or other shape.

The crucible is controlled by film thickness monitoring system, it can change the material automatically and achieve complex coating films precisely.
Film Thickness Control
Professional INFICON SQC-310 is equipped on the machine to serve the film thickness measuring and controlling, the system could process coating automatically by your pre-set evaporation curve, and the operations such as select the scaning frequency and amlitude, crucible ratation to change material, evaporation speed, shield plate motion and gas filling will be decided by program interlligently.

Max. 100 layers of coating film could be controlled by SQC-310

Total 50 different process could be restored on the system, the operator can recall any process to repeat the production quickly.

Industry PC, PLC, 19" touch screen operation panel and bus communication compose of automatical operation system.
