Microscope usage guidelines and precautions
(1) Eyepiece and objective lens: These two are the core structure of the microscope, they work together to magnify the observation object.
(2) Reflector and shutter: the key components of light adjustment.
① Reflector: Its design is ingenious, it can change the path of light by rotating, so that the light is reflected to the observer through the light hole. It is usually equipped with two sides, one side is a flat mirror and the other side is a concave mirror to adapt to different light conditions.
② Light shutter: This part is equipped with different sizes of apertures, these apertures can be aligned with the light hole, so as to achieve fine adjustment of the light intensity.
[Method tips] Light adjustment
When the light is strong, in order to prevent the field of view from being too bright, we can choose to use a flat mirror and cooperate with a small aperture to adjust to a suitable brightness. On the contrary, when the light is weak, in order to ensure the clarity of the field of view, we will use a concave mirror and a large aperture to adjust the light intensity.
Next, let's take a look at the two helices in the microscope. The coarse quasi-focal helix is mainly responsible for making the lens barrel obviously rise or fall, while the thin quasi-focal helix is responsible for fine-tuning, further making the object image clearer.
