Abstract
A spectral image sensor includes: a first lens system; an infrared blocking filter; a second lens system configured to adjust a chief ray angle (CRA) of oblique incident light to reduce an incident angle of the oblique incident light with respect to a spectral filter; the spectral filter; and an image sensor. The image sensor may be configured to detect light passing through the first lens system, the infrared blocking filter, the second lens system, and the spectral filter.
Claims21
A spectral image sensor comprising:
- a first lens system comprising a plurality of lenses;
- an infrared blocking filter;
- a second lens system configured to adjust a chief ray angle (CRA) of oblique incident light to refract light passing through the second lens system to reduce a divergence of the light, and to reduce an incident angle of the oblique incident light with respect to a spectral filter, the second lens system contacting the infrared blocking filter;
- the spectral filter;
- and
- an image sensor;
- wherein the image sensor is configured to detect light passing through the first lens system, the infrared blocking filter, the second lens system, and the spectral filter,
- wherein the spectral filter is between the second lens system and the image sensor, and the spectral filter contacts the image sensor, and
- wherein the first lens system, the infrared blocking filter, the second lens system, the spectral filter, and the image sensor are provided in that order.
