Multi-channel array type optical sensing device and manufacturing method thereof

[0028]With reference to FIG. 1 for a cross-sectional side view of a multi-channel array type optical sensing device in accordance with the present invention, the multi-channel array type optical sensing device 10 comprises an encapsulating housing 11, and at least one electrical contact (or soldering contact point) 15 disposed on a side (a side surface or the bottom) of the encapsulating housing 11 and provided for combining with an external electronic device (not shown in the figure). As the name suggests, the encapsulating housing 11 such as a hard shell or other enclosures with a protective function can protect and prevent the electronic components in the encapsulating housing 11 from being contaminated with dust or dirt. The encapsulating housing 11 also can protect the electronic components therein from being hit and damaged by external forces.

[0029]The encapsulating housing 11 comprises a printed circuit board 14, a light receiving unit 13 and a filter array 12. The filter arr...

[0035]With reference to FIG. 6 for the cross-sectional side view of a multi-channel array type optical sensing device in accordance with the present invention, the difference between this embodiment and the aforementioned embodiments resides on that the transparent protective layer 27 and the filter array 22 of this embodiment are stacked together as a whole, and a transparent adhesive is used for adhesion to prevent the light from being refracted.

[0036]By using the filter array formed by the filters of different wavelengths for the division of light, and the non-continuous light division method for the biological test, the manufacturing cost of the multi-channel array type optical sensing device of the present invention can be reduced significantly, and the light characteristics of the testing object can be used for the configuration of the wavelength of the filters of the filter array. In addition, the stacked structure of the optical components of the multi-channel array type opt...
