Description

TECHNICAL FIELD

[0001] The utility model relates to inverted microscope accessory technical field especially, it relates to a kind of inverted microscope stage heating device. BACKGROUND

[0002] In biomedical, cell culture, material science and many research fields, it is often necessary to observe and analyze samples under microscope. For some temperature-sensitive experiments, such as cell observation, biochemical reaction process monitoring, etc., it is crucial to maintain the sample in a suitable and stable temperature environment. However, traditional inverted microscope stages generally do not have heating function, or their heating devices have problems such as uneven heating, low temperature control precision, complex structure, difficult to install and maintain, etc., which cannot meet the needs of high-precision experiments.

[0003] For example, a general optical microscope stage constant temperature heating device with publication (announcement) number CN220933271 U is closely attached to the stage, which can maintain constant temperature and does not affect the operation of the microscope. The constant temperature heating device is composed of a heating module and a constant temperature control module. The heating module is mainly composed of a heating film. The heating film is installed on the microscope stage after being perforated, and is closely attached to the stage.
