Culture microscope apparatus
View Patent ↗A culture microscope apparatus has an illumination unit to apply excitation light to the specimen, a specimen observing portion to observe light generated from the specimen due to the excitation light, and a dimmer unit to dim the excitation light that has penetrated the specimen.
1. A culture microscope apparatus comprising:
(i) an optical system for observing a specimen, the optical system including an objective lens to observe the specimen;
(ii) a culture device defining at least three regions including:
a region I where temperature and humidity are maintained at a level equal to that in an environment inside a body of a human being or an animal by the culture device,
a region II, which is provided in a space not including the region I and adjacent to the region I, and where the temperature is on a level equal to that of the region I and the humidity is maintained at a normal humidity level by the culture device, and
a region III, which is provided in a space under the region I and the region II and adjacent to the region II, on a normal temperature and normal humidity level outside of the culture device,
wherein the specimen is located in the region I, and the objective lens extends through a boundary between the regions I and II; and
(iii) a transparent optical member that is positioned on a boundary between the regions II and III, the transparent optical member being located on an optical axis of the optical system, so that light for the optical system passes through the boundary between the regions II and III.
2. The culture microscope apparatus according to claim 1 , wherein the optical system includes an image pickup device for picking up an image of the specimen, and the image pickup device is located in the region III.
3. The culture microscope apparatus according to claim 2 , wherein the regions I, II, and III are located along the optical axis of the optical system, and the specimen, the objective lens, and the image pickup device are located along the optical axis.
4. The culture microscope apparatus according to claim 2 , wherein the regions I and II satisfy the following conditional equations:
36° C.≦t1≦38° C., 90%≦h1≦100%
36° C.≦t2≦38° C., 50%≦h2≦80%
where t 1 indicates the temperature of the region I, h 1 indicates the humidity of the region I, t 2 indicates the temperature of the region II, and h 2 indicates the humidity of the region II.
5. The culture microscope apparatus according to claim 1 , wherein the regions I and II satisfy the following conditional equations:
36° C.≦t1≦38° C., 90%≦h1≦100%
36° C.≦t2≦38° C., 50%≦h2≦80%
where t 1 indicates the temperature of the region I, h 1 indicates the humidity of the region I, t 2 indicates the temperature of the region II, and h 2 indicates the humidity of the region II.
6. A culture microscope apparatus comprising:
(i) an optical system for observing a specimen, the optical system comprising an objective lens to observe the specimen, and an image pickup device to pick up an observation image of the specimen;
(ii) a culture device defining at least three regions including:
a region I where temperature and humidity are maintained at a level equal to that in an environment inside a body of a human being or an animal by the culture device,
a region II, which is provided in a space not including the region I and adjacent to the region I, and where the temperature is on a level equal to that of the region I and the humidity is maintained at a normal humidity level by the culture device, and
a region III, which is provided in a space under the region I and the region II and adjacent to the region II, on a normal temperature and normal humidity level outside of the culture device,
wherein the specimen is located in the region I, the objective lens extends through a boundary between the regions I and II, and the image pickup device is located in the region III.
7. The culture microscope apparatus according to claim 6 , wherein the regions I and II satisfy the following conditional equations:
36° C.≦t1≦38° C., 90%≦h1≦100%
36° C.≦t2≦38° C., 50%≦h2≦80%
where t 1 indicates the temperature of the region I, h 1 indicates the humidity of the region I, t 2 indicates the temperature of the region II, and h 2 indicates the humidity of the region II.
