GENERAL HISTOLOGY

Detailed explanation-1: -Field of View = Field Number (FN) ÷ Objective Magnification When you switch eyepieces or objective lenses, ensure to repeat the FOV calculations with the new inputs on field number and magnifications. For objects that require higher magnifications, convert your measurements from millimeters to micrometers.

Detailed explanation-2: -Calculation of Actual Size: To calculate the actual size of a magnified specimen, the equation is simply rearranged: Actual Size = Image size (with ruler) ÷ Magnification.

Detailed explanation-3: -Based on optical physics, the diameter of the field of view can be reliably derived by a simple formula: Diameter of the field of view (mm) = F / M, where F is the number of field of view (FOV) of the eyepiece, and M is the magnification (mag.) of the objective.
