US 2017/0322158 A1 · SPECIMEN DETECTION DEVICE AND SPECIMEN DETECTION CHIP

Abstract

According to one embodiment, a specimen detection device includes a light source, a filter, a sensor, and a controller. The light source executes a first operation and a second operation. The first operation causes a first light of a first peak wavelength to be incident on a specimen. The second operation causes a second light of a second peak wavelength to be incident on the specimen. The filter attenuates the first and second lights and transmits at least a portion of a third light and at least a portion of a fourth light. The third light is emitted from the specimen. The fourth light is emitted from the specimen. The sensor outputs a first signal and a second signal. The first signal corresponds to the third. The second signal corresponds to the fourth light. The controller calculates a result value by processing the first and second signals.

Dependent claims

A specimen detection chip, comprising:

a sensor including a plurality of detection elements;
a wall unit separated from the sensor along a stacking direction;
and
a filter provided between the sensor and the wall unit, the filter attenuating a first light of a first peak wavelength and transmitting a light of a wavelength longer than the first peak wavelength,
the plurality of detection elements being arranged at a first pitch along a first direction intersecting the stacking direction,
the wall unit partitioning a plurality of spaces capable of containing a specimen,
the plurality of spaces being arranged at a second pitch along the first direction,
the second pitch being not less than 0.95 times and not more than 1.05 times an integer multiple of the first pitch.
