Welcome to this virtual laboratory experiment. In this simulation, you will learn how to determine particle size distribution using microscopic methods. This is an important technique used in materials science, geology, and many other fields.
You will calibrate the stageometer, observe particles under the microscope, and analyze their size distribution.

Stage Micrometer Calibration
1. One division on stage micrometer scale = 10 µm
2. Number of divisions of stage micrometer scale coinciding = X
3. Number of divisions of eyepiece micrometer scale coinciding = Y
Calculation: If Xth division on stage micrometer = Yth division on
eyepiece scale, X × 10 Then, One division on eyepiece scale = μm Y
Enter Stage Divisions (X)
Enter Eyepiece Divisions (Y)
