Abstract
An embodiment provides an optical signal detection device including a sample holder configured to accommodate a plurality of samples, a light source module including a plurality of light source units dedicated to each sample area to irradiate light to a plurality of sample areas on the sample holder, a filter module including a plurality of movable moving units for filtering light from the light source unit and a detection module configured to detect emission light of the sample.
Claims17
An optical signal detection device, comprising:
- a sample holder configured to contain a plurality of samples, wherein the sample holder is divided into a plurality of sample areas, each of the sample areas comprising a group of reaction sites;
- a light source module configured to irradiate light to the plurality of sample areas, wherein the light source module comprises a plurality of light source units comprising a first light source unit and a second light source unit, wherein each of the plurality of light source units is arranged to irradiate light to different sample areas, and wherein one dedicated individual light source unit is allocated to each of the sample areas, and wherein each of the plurality of light source units comprises at least one light source element;
- a movable filter module that filters light emitted from the light source units, wherein the filter module includes a plurality of filter units comprising a first filter unit and a second filter unit, wherein when the first filter unit is configured to be positioned in an optical path of the first light source unit, the second filter unit is configured to be positioned in the optical path of the second light source unit;
- moving means configured to move the filter module so that the first filter unit may selectively filter light emitted from the first light source unit or the second light source unit;
- and
- a detection module configured to detect emission light emitted from the sample area,
- wherein the plurality of filter units are arranged so that the plurality of light source units irradiate light to each sample area through different filter units.
