How to Calculate the Magnification of a Stereomicroscope?
"How is the magnification of a stereomicroscope calculated?" We frequently receive inquiry calls of this kind from customers during sales. Here we provide a detailed explanation for your reference.
The microscopes we supply include stereomicroscopes and monocular video microscopes. Essentially, monocular video microscopes are derived from stereomicroscopes. Integrated optical, mechanical and electronic components enable observers to magnify microscopic specimens for better observation and analysis.
First, let us look at how the magnification of a stereomicroscope is determined. The magnification of a stereomicroscope consists of objective magnification and eyepiece magnification. Total magnification of stereomicroscope = Objective magnification × Eyepiece magnification
Example: For the MZS0870 stereomicroscope, the objective is set to the 6.5× mark, a 20× eyepiece is used, and a 0.5× auxiliary objective is attached. Total magnification = 6.5 × 20 × 0.5 = 65×
Next, we introduce the magnification calculation method for monocular video microscopes: Total magnification = Optical magnification × Digital magnification Digital magnification = Diagonal size of the display screen / Diagonal size of the CCD sensor target
Diagonal dimensions of CCD sensors:
1/3 inch CCD: 6 mm
1/2 inch CCD: 8 mm
2/3 inch CCD: 11 mm
Example: Digital magnification for a 14-inch monitor paired with a 1/3-inch CCD camera = 14 × 25.4 / 6 = 59.27
