Abstract
A fluorescence imaging device includes a microplate that holds a plurality of samples generating fluorescence, a lens assembly, and an imaging unit that collectively images the plurality of samples through the lens assembly. The lens assembly includes a Fresnel lens made of a resin, a second protective plate that protects the surface of the Fresnel lens facing the microplate, a spacer that forms a gap between the Fresnel lens and the protective plate, and a frame by which the Fresnel lens, the second protective plate, and the spacer are sandwiched.
Claims20
A fluorescence imaging device comprising:
- a microplate that holds a plurality of samples generating fluorescence;
- a lens assembly that is disposed above the microplate, and includes a Fresnel lens of which at least a side facing the microplate is telecentric and which is made of a resin, a protective plate that protects a surface of the Fresnel lens facing the microplate, a spacer that forms a gap between the Fresnel lens and the protective plate, and a frame by which the Fresnel lens and the protective plate are sandwiched through the spacer;
- and
- an imaging unit that collectively images the plurality of samples through the lens assembly using the fluorescence generated by the respective samples.
