  • OPTICAL SENSING DEVICE
    Publication number: 20250098361
    Abstract: A optical sensing device includes a substrate, an optical acting area and a filter layer. The optical acting area is disposed on the substrate. The filter layer covers the optical acting area and selectively allows only a light beam with a specific wavelength to pass through and be received by the optical acting area while blocking the light beams with other wavelengths. Each of the two sides of the substrate has a bevel structure. The filter layer covers each bevel structure of each side to prevent the light beams with other wavelengths from passing through the two sides of the substrate being received by the optical acting area.
