Abstract

According to an aspect of the invention, an observation system includes at least one observation apparatus and a thermostatic bath. The observation apparatus includes an imaging unit, a temperature sensor, and first control circuitry. The imaging unit captures an image of the sample. The temperature sensor measures an internal temperature of the observation apparatus. The first control circuitry estimates a sample temperature based on the internal temperature and calculates an indication temperature based on the sample temperature and temperature distribution data of the thermostatic chamber. The thermostatic bath includes a memory and second control circuitry. The memory stores the temperature distribution data. The second control circuitry performs the temperature control by setting a set temperature based on the indication temperature.

Dependent claims

An observation system, in a state in which at least one observation apparatus is placed in a thermostatic chamber of a thermostatic bath together with a sample to be observed, in which the observation apparatus and the thermostatic bath communicate with each other and temperature control in the thermostatic chamber is performed based on a set temperature, the observation system comprising:

the observation apparatus comprising:
an imaging unit configured to capture an image of the sample;
a temperature sensor configured to measure an internal temperature of the observation apparatus;
and
first control circuitry configured to estimate a sample temperature, which is a temperature of the sample, based on the internal temperature and calculate an indication temperature indicated to the thermostatic bath as the set temperature based on the sample temperature and temperature distribution data acquired from the thermostatic bath through the communication;
and
the thermostatic bath comprising:
a memory configured to store the temperature distribution data of the thermostatic chamber;
and
second control circuitry configured to perform the temperature control by setting the set temperature based on the indication temperature acquired from the observation apparatus through the communication.
