Abstract: The present disclosure relates to an optical filter and a method of producing the same. In the producing method, a thermal evaporation deposition process of a sacrificial layer, and depositions process of a base layer and a dielectric stack layer are sequentially performed on a substrate having a trench with a specific width, so that the base layer and the dielectric stack layer extend outward to form a solidified structure with a specific length. Next, a fixed layer is affixed to the dielectric stack layer, and the sacrificial layer is removed using a solvent to remove the substrate. As such, structural strength and flatness of the produced optical filter are enhanced, and a volume thereof is reduced, such that the optical filter can be applied to automated processes of miniaturized elements.

Abstract: The disclosure provides a charger including a base and a charging circuit. The base includes a coupling portion for detachably coupling with one of multiple supporting stands. Each of the supporting stands has a supporting container with different standards. The coupling portion has a coupling surface. The coupling surface is used for supporting one of the supporting stands. The charging circuit is disposed in the base and the charging circuit has a first electrical connector. The first electrical connector protrudes from the coupling surface. When the coupling portion is coupled with the supporting stand, a portion of the first electrical connector is disposed in the supporting container.
