Optical Lens Coating MachineYour position: Home > Optical Lens Coating
|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 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
|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.
|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
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.
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
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
