Microscope Calibration

Microscope CalibrationMicroscope calibration can help ensure that the same sample, when assessed with different microscopes, will yield the same results. Even two identical microscopes can have slightly different magnification factors when not calibrated.

The scale on the eyepiece reticle does not have units and the values change at different magnifications. Therefore, it is important to calibrate the eyepiece reticle before taking measurements to ensure that the microscope will output accurate and valid information.

Let Us Care For & Calibrate Your Microscope

The Microscope Calibration Process

The size of objects in the microscope’s field of view differs at each magnification, so the actual diameters of these fields of view need to be calculated through calibration. The process of microscope calibration is a comparison of the grid on the eyepiece reticle with a stage micrometer showing units in millimeters or micrometers to validate the scale. When calibrating, the stage micrometer is lined up with the grid on the reticle, then the number of divisions on the microscope are counted per millimeter or micrometer on the staged micrometer. The number of divisions will change as the magnification changes.
