EB Optical Coating Machine
Optical films are widely used in various daily necessities. Through the stacking and design of materials with different refractive indexes, the optical interference phenomenon is used to produce various effects of light, and optical multilayer films with different functions.
Colored decorative film give sunglasses or swimming goggles an attractive color appearance; high-reflective mirrors can be applied to the back light to enhance the uniformity of reflected light and increase lighting efficiency. Filters with different functions can also be designed according to requirements.
Dah Young's DMC-EB series optical equipment has a high degree of process flexibility. The configuration of multiple crucibles can complete the multi-layer film process in vacuum, increasing the output efficiency. And through the quartz oscillator, the film thickness and plating rate are accurately monitored to improve the process stability.
