apex series
Optimized system for AR on Ophthalmic Lenses
apex series is specialized and optimized only for AR (Anti-Reflection) coating on ophthalmic lenses from Rx to Stock production apex has been verified for long time by major lens manufacturers and has proved its excellent productivity and reliability.
Top Coat Special Coat (ITO)
produced by a high vacuum coating machine
AR Coat
Hard (Base) Coat Lens (substrate)
As light passes through an uncoated lenses, approximately 8% will be reflected. As a result of this, reflection of image and light haze irritate wearers and anyone facing him or her. This reflection can be reduced by the application of anti-reflection coating based on interference effect, which can improve the visibility and aesthetical effects of wearers. This coating can be made under high vacuum conditions and by controlling the thickness of multi-layers precisely.
Remarkable Reproducibility, Uniformity, Productivity
Using a separate uniformity mask per evaporation material, the difference of uniformity caused by characteristics of a material can be minimized. 200 lenses (diameter 70mm) can be coated at a 1,200mm-diameter-chamber
Reproducibility for 4 batches in series 4.0 3.5 3.0 Reflectance (%)
Optimizing and stabilizing core components and structure minimize the change of conditions during coating process. Besides, applying HOMS (Hanil Optical Monitoring System) enhances the reproducibility batch to batch.

Fast and Stable Pumping, and Durability The innate durability from design prevent Real Leak and Crack from being made over a long period of use. And apex has the sufficient capability of pumping so as to finish one batch within or around a half hour.
Easiness (User Friendly Interface) apex is the fully automated system so that even a layman can use it easily. By using HOPE (Hanil Optical Process Executor), process management software, an operator can manage from recipe making, process monitoring and control, to production history (data log) control. Since every critical parameters during coating process are saved automatically, he or she can use it as reference data when he or she faces defective batches to trace and estimate potential causes.
