Partnership

The optics is a high knowledge intensive discipline. Most purchasing customers do not exactly understand optics or optical filter he need. Worse than that, there is no standard optical filer to customer products.

Every optical filter has its own characteristic required by different customers. Even two different customers make the same function product, the optical filters they required are still different. One coating producer will also make his optical filter different to another coating producer. This is because they use different coater and adapt different layer designs. There are too many characteristic can't be regulated in specification. Such as thin film addsive force, surface quality, visual color (not necessary related or can be requlated in spectrum specification) are all different to different coating producer. The customer cannot distinguish which coater is best for his products. Only coating producer can do.

Base on customer requirements, we realize a professional coater (especially flat glass optical filter) need to be a long term supplier to a customer.
