6) Stage Clips – clips that keep the slide or specimen from movingon the stage
magnification lens with the highest power
5) High Power Objective –

14) Arm –
moves the body tube in small increments
moves the body tube in large increments
attaches the eyepiece and the body tube to the base

Calculate Total Magnification
Total Magnification =
ocular power x objective lens power using
Ocular power is generally 10X, meaning it has a magnification or power of 10X
