Abstract
As light is allowed to impinge from above a microplate M and an imaging unit 13 (a line sensor 131 and an imaging optical system 132), which moves in a scanning motion along the bottom surface of the microplate M, receives transmitted light, images of wells W formed in the microplate M are captured. The scope of imaging by the line sensor 131 is greater than the diameter of at least one well W, or preferably, encompasses a plurality of wells. When the depth of field of the optical system 132 is 0.6 mm or less, the influence of reflection of side walls of the wells upon the images is reduced.
Claims10
An imaging apparatus for imaging a sample plate whose surface has a plurality of wells which are capable of holding a fluid, comprising:
- an illumination member which irradiates light from above the sample plate which is in a horizontal condition;
- and
- an imager member which receives transmitted light which is transmitted to below the sample plate and captures an image which includes at least one of the wells,
- wherein the imager member includes an imaging element and an optical system which focuses the transmitted light upon the imaging element, and a depth of field of the optical system is equal or smaller than 0.6 mm.
An imaging method of imaging a sample plate which has a plurality of wells which hold a liquid-state or solid-state culture medium, comprising the steps of:
- irradiating light from above the sample plate which is in a horizontal condition;
- and
- capturing an image containing at least one of the wells by an imaging element while the optical system focuses a light transmitted to below the sample plate upon the imaging element, wherein
- a depth of field of the optical system is equal to or smaller than 0.6 mm.
