Paper Abstract

In this paper, a high-integration multi-spectral imaging lens was developed by micro-fabrication technology. By using multiple photo-etching and thermal reflow process, a microlens array and a multi-channels filter were integrated together without position mismatch. Besides, light block layer and isolation layer were brought in the structure to improve the imaging quality. Its fabrication process is described in detail and the optical property was tested by imaging experiments. The multi-spectral imaging lens has 9 optical channels, each channel capable of filtering and imaging independently. The imaging results indicate that the lens can capture pictures of visible bands and near-infrared band at the same time. Because of its high level of integration and image parallel capture capability, the novel lens is suitable to be applied in extracting conceal information and biomedical imaging.
