Abstract
The optical sensor device including a sensor layer, a microlens layer and a filter layer is provided. The sensor layer includes a plurality of sensor areas, and is configured to sense a multi-wavelength light from a finger. The microlens layer includes a plurality of microlenses arranged in an array, and is disposed on the sensor layer. Each of the microlenses focuses the multi-wavelength light on a corresponding one of the sensor areas. The filter layer is disposed between the sensor layer and the microlens layer, and configured to filter the multi-wavelength light to generate a plurality of lights with different wavelengths. In addition, the fingerprint sensor apparatus including the foregoing optical sensor device is also provided.
