The stage
light is collected by a mirror at the base of the microscope. The mirror is held in special joints that allow it to move in any direction. The light comes from a lamp or from a sunless sky. It must never be collected directly from the sun as this can cause sever eye damage and blindness. Some microscopes have a built-in lamp instead of a mirror. The light either shines directly through a hole in the stage onto the specimen or it passes through a hole in a diaphragm.
It is a black hole - which is not a star.
It is called a volcano, the hole is for the lava to come out.
Black hole
it's the STAGE

the glory hole, duhhhComment: It's not the 'glory hole' so 'duhhh' to you too!
i think its i a microscope love.
You can have a source of light underneath the stage, that will shine through the hole and illuminate the subject that you are looking at.
it reflects light up through the hole in the stage and onto the slide.
It changes the amount of light going through the hole in the stage.
A compound microscope can either have a light bulb or a mirror for illumination. If your microscope has a mirror, then you need sunlight or some other light source to point at the mirror to view your slide.The mirror is used to focus light up through the hole in the microscope's stage, or slide platform. The slides will contain a thin slice of material through which the light can shine, to reveal the internal structure of the sample.
The aperture of a microscope refers to its light-gathering capability and ability to resolve fine detail. It is usually used in reference to photomicrography.
So the light can shine through. If there is no light reaching the lens and surrounding the subject, then one would be unable to see
It is called an aperture.
The stage in a microscope holds the specimen, usually on a slide, and has an opening in it to permit light to come up through the stage and through the specimen and further on up to the optics.
