It is the point at which all light rays seem to diverge from in the case of a concave mirror
I think to focus light on the specimen slide.
focus
The concave mirror reflects the bulb's light, and if the bulb is at the mirror's focus, sends it out as a parallel beam.
In flood lights,the source of light is placed between the pole and focus of a concave mirror so as to obtain a diverging beam of light..
In front of the mirror
A concave mirror would focus the light back towards the focal point of the mirror. You would not be able to use the mirror effectively with a concave.
A concave mirror cause light rays to converge at the focus

concave mirror and convex lens can be used to focus light rays. they are also called converging mirror and lens respectively. They focus the light at a distance of its focal length.

A concave mirror will tend to "focus" light to some degree, depending on the curvature of the mirror. A parabolic mirror will bring reflected light to a sharp focus, and telescopes use this type of curve for the shape of their reflective surface. And for exactly the reasons you think they do.

a detist use concave mirrors to focus light on the tooth because when objects are kept very closee to concave mirrors they look larger, this makes concave mirrors useful for a dentist to focus light on the tooth.
A parallel light source will reflect off a concave mirror and go through a point inside the curve called the focus. Reflecting from a convex mirror will cause all light to bounce off in a straight line away from a focus point behind the mirror.
