At present, blue glass filter has been widely used in middle and high-end projects. With the continuous improvement of technology and cost optimization, the use of blue glass filter will be more extensive. Blue glass has two advantages over ordinary reflective IR: on the one hand, blue glass has a congenital advantage in terms of material characteristics, and it can avoid the ghost phenomenon caused by reflection by absorbing the infrared band light; on the other hand, blue glass has a smaller drift of spectral curve for light at different incident angles, so it is necessary to be able to make this blue glass filter There is no lack of coating technology, the role of optical coating machine in this process is indispensable.

The blue glass filter produced by optical coating machine has been applied to mobile phone electronic products or other products. Of course, there are many coating technologies in the optical coating of mobile lens, and it is difficult to explain all the simple sentences clearly.
