Description

Technical Field

[0002] Optical films are everywhere in our lives, from precision optical equipment, display equipment to daily optical film applications; for example, glasses, digital cameras, various home appliances, or anti-counterfeiting technology on banknotes can all be called extensions of optical film technology applications. Without optical film technology as a development foundation, modern optoelectronics, communications or laser technology will not be able to develop, which also shows the importance of the development of optical film technology.

[0003] Optical thin film refers to a layer or multiple layers of electrolyte or metal film plated or coated on an optical element or independent substrate to change the transmittance of the spectrum, including the transmission, reflection, absorption, scattering, polarization and phase change of light.

Therefore, we propose a preparation device for optical film leakage prevention. By marking the transparent and difficult-to-identify defective waste with color, it is convenient for the optical film to be cut, avoid leakage and play a positioning mark role, and ensure the stability of the optical film size.
