Title:
SPECTRUM INTENSITY MEASUREMENT ELEMENT
Document Type and Number:
Japanese Patent JP2008232843
Kind Code:
A
Abstract:

To provide a spectrum intensity measurement element capable of measuring the spectrum intensity of light without using spectrum filter.

The measurement element is composed of the light sensor 1 provided with a plurality of light receiving parts arranged toward in a direction with a prescribed pitch and the surface of the region arranged with the light receiving parts is formed in a flat surface and the optical member 12 which comprises the light incident surface 13 on the reverse surface of the opposite surface to the light sensor 1 and the outgoing surface 14 whose distance to the surface of the arranged region of the light receiving parts is continuously varied from one end of the plurality of light receiving parts toward the other end in an arranged direction and the spectrum gap 15 is formed between the outgoing surface 14 and the surface of the light receiving part arranged region of the light receiving sensor 1.
