EB-IAD 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.
The anti-reflection film can make the camera function of the mobile phone clearer and reduce the ghosting on the lens; the UV/IR cut-off filter can protect the operation of the sensor and related components, improve the image stability and increase the service life, and be applied to fingerprint unlocking under the screen. Optical coatings can achieve different purposes through multi-layer film stacking, or by increasing or decreasing in thickness. Therefore, filters with different functions can be designed according to requirements.
Dah Young's DMC-IAD series optical equipment has a unique optical monitoring system, which can measure the wide-wave domain spectrum in the chamber cavity to calculate the refractive index in vacuum, make tooling value calculation easier, and quickly correct the film parameters. The admittance trajectory algorithm can be used to easily compensate the film thickness error, and the film tangent point can be effectively selected to complete the high-quality film.
