From the geometry of the spherical mirror, note that the focal length is half the radius of curvature: As in the case of lenses, the cartesian sign convention is used here, and that is the origin of the negative sign above. The radius r for a concave mirror is a negative quantity (going left from the surface), and this gives a positive focal length, implying convergence.
HOW TO DETERMINE YOUR FIELD OF VIEW UNDER A SPECIFIC MAGNIFICATION IN MILLIMETERS . 1) Look at your microscope eyepiece. After the eyepiece magnification you will see a F.O.V, number. (Example: 10x/22 The 22 is your Field Number) 2) Use the following formula to obtain the total diameter: Formula = Field Number Divided by Objective Magnification
