TH25440B - Ultra-low residue reflection lens coating And low stress - Google Patents

Abstract

DC60 (04/06/47) provides a method for coating optics and surface optics equipment. Resist light reflection These lenses have low reflectivity. Gives white reflected light and low-stress anti-reflective coating. Which is suitable for optics created by A die-casting process that achieves low-stress lenses. Another feature is this method uses a coating compound. Special containing one substance is a substance with a high refractive index. And the other substance has a low refractive index. Another feature, the methodology, revealed the use of an optometrist in conjunction with conventional vapor coating, where an optical reference lens was used and reflected light was measured at a specific frequency. And take the measured value Used to indicate whether the desired optics thickness has been achieved or not. Another feature is that this method should be Calculate the optical thickness of each layer using a specific ratio of blue light to white light and to red light in the reflected light. The stress of the anti-reflective coating layer has also been Controlled by adjusting the optical thickness of each layer (if necessary) to reduce the difference between Tensile and compressive stress Between the low refractive index layer and the lowest refractive index layer, a method for coatings of optical optics and surface optics is provided.

Another feature is that the method reveals the use of an optical transducer in combination with conventional vapor coating, where an optical reference lens is used and the reflection is measured at a specific frequency. And take the measured value It is used to indicate whether the required operational thickness is achieved or not. Another feature is that this method should be The visual thickness of each layer was calculated using a specific ratio of blue light to white light and to red light in the reflected light. The stress of the anti-reflective coating layer has also been Control by adjusting the visual thickness of each layer (if necessary) to reduce the difference between Tensile and compressive stress Between the low refractive index layer and the lowest refractive index layer
