Optical Vapor Deposition Coating Machine
Optical films are used in a variety of products. By coating the substrate using multiple and different layers, the optical interference produces various effects of color and functions.
The anti-reflective coating can make the camera function of the mobile phone clearer and reduce ghosting on the lens.The long-wavelength filter coating can reduce the blue light emitted by a screen to protect the eyes; the color coating provides sunglasses and goggles optional color appearance and added eye protection; the mirror coating can be applied to enhance the intensity of the reflected light, to make the illumination clearer, and to design filters of different wavelengths according to requirements.
Dah Young's DMC-EB series optical equipment has a unique optical monitoring system, which can measure the broad-wavelength spectrum in the chamber cavity to calculate the refractive index in a vacuum. The algorithm of the admittance trajectory can be used to effectively select the optimum coating time to achieve the desired coating finish.
