Abstract: An eyeshade structure for bilirubin detection includes a body, a first detection module, and a second detection module. The body includes a bottom plate and a side wall. The side wall is connected to the bottom plate and forms an accommodating space with the bottom plate. The first detection module is arranged on the bottom plate. The second detection module is arranged on the bottom plate and is adjacent to the first detection module. The first detection module and the second detection module each include a circuit board, a light-emitting element, an inner photographing element, and an outer photographing element. The circuit board is connected to the bottom plate. The light-emitting element is electrically connected to the circuit board. The inner photographing element is electrically connected to the circuit board. The outer photographing element is electrically connected to the circuit board.

Abstract: A polarizer includes a first polarization layer group. The first polarization layer group includes a first light-transmitting layer and a second light-transmitting layer. The first light-transmitting layer has a first X-direction refractive index and a first Y-direction refractive index. The second light-transmitting layer is superimposed on a top surface of the first light-transmitting layer. The second light-transmitting layer has a second X-direction refractive index and a second Y-direction refractive index. The first Y-direction refractive index is different from the second Y-direction refractive index, and the first X-direction refractive index is essentially the same as the second X-direction refractive index. The second light-transmitting layer has a first light-transmitting medium and a second light-transmitting medium arranged transversely, and a third refractive index of the first light-transmitting medium is different from a fourth refractive index of the second light-transmitting medium.

Abstract: A wire gating polarizer includes a substrate layer, a polymer wire grating layer and a plurality of coated layers. The polymer wire grating layer is disposed on the substrate layer, and includes a plurality of wire grating units. The plurality of wire grating units are formed on an upper surface of the substrate layer, and extend in a first direction. Each of the wire grating units has a top surface and respectively has a first side surface and a second side surface along two sides of the first direction. The plurality of coated layers are respectively formed on the first side surface of each of the wire grating units. The plurality of coated layers are made of a metallic or nonmetallic dielectric material. A manufacturing method of the wire grating polarizer is further provided.
