An optical microscope used in a laboratory would have 3 different types of lenses.They are :-(1) Condenser lens- directs light to the specimen if there is no in built light source.(2) Eye piece - lens close to the eye of the observer which magnifies the image created by the objective lens.(3) Objective - These are the lenses which are positioned closest to the specimen mounted on the stage of the microscope which magnifies the specimen. There could be several objective lenses in an optical microscope, generally three. The low power objective (usually magnifies 4 times), mid power objective (usually magnifies 10 times) and the high power objective (usually magnifies 40 times).
One meaning of cover slip in a biological context is a thin small rectangular piece of glass that one would lay over a specimen mounted on a microscope slide in order to hold it steady, flatten it out and protect it.

If you start at the tip of the scope the first thing that you look into is the eyepiece or Ocular. Through the ocular you now are looking down the Tube. Some tubes have prisms and/or mirrors to move the light around. The objective that you screw into the bottom of the tube passes light also.
I think to focus light on the specimen slide.
Total magnification is determined by multiplying the magnification of the ocular lens by that of the objective lens. Compound microscope that uses more than one lens to direct light through a specimen mounted on a glass slide.
A coverslip in Biology is a small rectangle of glass that is mounted on a slide to be viewed under a microscope. The coverslip protects the specimen, keep it in place and/or make it flat.
On the microscope stage (after it has been mounted on a glass microscope slide).

Hooke's compound microscope was consisted of two thick lenses at either end of the eyepiece, which looked much like a kaleidoscope. The specimen was mounted on a pin at the end of the eyepiece and beside the pin was a globe full of liquid (usually water) to give the image an illusion effect. The light to produce the image of the specimen was simply an oil lamp with a small circular mirror.

are thin slides of rock or mineral mounted to a microscope slide.
