Multi-Angle Coated Optical Sensor
Patent No.M639464 Date of patents：2023.04.01
A multi-angle coating optical sensor comprises a sensor, an oxide layer, a silicon nitride layer, and an optical multilayer stack, the optical multilayer stack is provided with layers of optical films totaled 13 layers, the surrounding of the sensor is covered with the oxide layer so that the oxide layer forms a barrier. The sensor is covered with a silicon nitride layer in the area without the oxide layer, and the silicon nitride layer is covered with the optical multilayer stack. The oxide layer can partially block the light source; therefore, the optical multilayer stack creates an interference effect to increase transmittance or reflectance of the light and enhance the variations of the incident angles through the optical film, resulting in a better control of the incident light source and a low loss of the incident light source.
Virtual Reality Optical Component Structure
Patent No.M639545 Date of patents：2023.04.01
A virtual reality optical element structure comprises a prism and a coating plastic body, the plated plastic body is equipped with several beveled plastic parts and an optical multilayer stack, the optical multilayer stack is coated on the several beveled plastic parts, and the several beveled plastic parts are combined with each other under pressure so that the several beveled plastic parts can form multiple refraction angles relative to the optical multilayer stack. The prism is set on the top side of the coating plastic body, the incident light is refracted through the prism to the coating plastic body to form a three-dimensional image. This creates a composition which is overall thin and lightweight, down-sized in applications, making it safer and more convenient to utilize, resulting in low risks as well as a thin and light integration.
Color Correction Coating for Optical Sensor Unit
Patent No.M644387 Date of patents：2023.08.01
A color correction coating design for an optical sensor unit comprises an oxide layer which is framed around the light sensor units, a silicon nitride layer which is applied on the surface of the optical sensor unit within the oxide layer framed area. A multi-layer optical coating is appled on the top of the silicon nitride layer, through the multi-layer optical coating and multiple reflection technology, the reflected light of the optical sensor unit is adjusted to the same chromaticity, and the color correction of the light sensor unit is unified into a uniform chromaticity.
Black Chrome Coating for Optical Sensor Unit
Patent No.M644510 Date of patents：2023.09.21
A black chrome coating design for an optical sensor unit comprises a substrate, a first section metallic absorbing film layer, and a second section reflectance maintaining film layer. The first section metallic absorbing film layer is applied on the substrate and the second section reflectance maintaining film layer is applied on the first section metal absorbing film layer. The first section metallic absorbing film layer can absorb stray light or unwanted light to further select a pure light source into the optical sensor unit, effectively improving a reflection efficiency of light while stably maintaining a reflection efficiency of light towards the optical sensor unit to achieve a structural stability and an optimal functional structure.
