Analysis device and analysis method

An analysis device comprising:

• a device holder configured to hold a microchamber device;
• a light source configured to irradiate the microchamber device with light;
• a plurality of aspheric lenses placed such that the optical axis thereof is substantially parallel to a normal line of a first surface of the microchamber device;
• an imaging apparatus holder configured to hold an imaging apparatus at a position that enables the microchamber device to be imaged via the aspheric lenses;
• a first optical filter positioned between the microchamber device and the imaging apparatus to be held, the first optical filter cutting off light emitted from the light source and allowing at least a portion of light having a longer wavelength than the wavelength of the light emitted from the light source to pass therethrough;
• and
• a light-shielding unit configured to suppress the detection, by the imaging apparatus to be held, of light other than light generated from the microchamber device and detected by the imaging apparatus to be held via the first optical filter and the aspheric lenses.
