Abstract: A method for adjusting output ratio of an optic sensor includes the following steps: measuring and obtaining a response spectrum of the optic sensor; analyzing optic response ratios of the response spectrum at different wavelengths; designing a ratio of light reception areas of the optic sensor, the design being carried out in accordance with three aspects of “the response spectrum” “a fixed proportional relationship being present between multiplication of the optic response ratio and the light reception area and an output of light current” and “a proportional relationship being present between the light reception area and the output of the light current”; and obtaining light current outputs of identical proportions (such as 1:1:1) or in a desired ratio (meaning any arbitrary ratio other than 1:1:1, such as 1:2:1, 1:2:3, or 3:4:5) in accordance with the design of the previous step.

Abstract: A structure of photodiode array includes a first electrode on which a plurality of second electrodes is arranged in a spaced manner forming an array and a plurality of isolation sections, which is each formed between adjacent ones of the spaced and arrayed second electrodes, whereby in carrying out tests of light currents, correct detection of the light currents can be realized to improve cross-talking between adjacent dodoes so as to effectively suppress interference of noise and alleviate the problem of low S/N ratio.

Abstract: A photo detection device includes a first lead frame, a second lead frame, a photo detection die having a coating layer, and an enclosure. The first lead frame forms a carriage section. The coating layer is formed on the photo detection die. The photo detection die is mounted on the carriage section of the first lead frame and forms electrical connection with the second lead frame through a conductor. The enclosure is a non-light-transmittable member forming therein a receiving space. The enclosure is mounted on the first and second lead frames and receives the photo detection die in the receiving space thereof. The enclosure forms an opening for light detection by the photo detection die. As such, detection of a long wavelength invisible light, such as an infrared light, by the photo detection die can be prevented to thereby provide a photo detection device with increased reliability of detection.
