DIGITAL MICROSCOPY

A guide on magnification levels on a digital microscope

Magnification refers to how many times a sample is reproduced and is a key factor in choosing the right microscope.

In this article, we will explain how magnification levels are calculated plus provide an overview of the magnification levels for each of of the TAGARNO digital microscopes.

 

WHAT DETERMINES MAGNIFICATION LEVELS

On a digital microscope, your sample is displayed on a monitor. To calculate magnification levels, you therefore need to know:

  • Size of the monitor you are using
  • Minimum and maximum field of view (in X direction) on that monitor

 

The monitor is important because the size of the monitor will determine how far you can zoom in and out. That is, you can reach lower AND higher magnification on a 27” monitor than a 24” monitor.

 

Example:
A TAGARNO FHD Prestige with a +10 lens can magnify an object 133 x on a 24” monitor. But it can magnify 145x on 27” monitor and 116x on a 22” monitor.

To understand why that is, let’s look at the math.

How to calculate magnification levels

The formula is quite simple: Just divide the width of the monitor with the minimum FOV to find the lowest possible magnification level. Then, divide the width of the monitor with the maximum FOV to find the highest possible magnification level.


Example:

You have a TAGARNO PRESTIGE with a +10 lens and a 24'' monitor.


To find the lowest possible magnification level, you say 531 mm (width of monitor) divided by 125.1 (minimum FOV), which equals to approximately 4.2x.

To find the highest possible magnification level, you divide 531 mm (width of monitor) by 4.1 (maximum FOV), which equals to approximately 129x.


This means, your object can be magnified between 4.2 and 129 times when using the FHD Prestige with a +10 lens on a 24'' monitor.

MAGNIFICATION LEVELS ON TAGARNO DIGITAL MICROSCOPES

Below is a table with the magnification levels for each of the lenses that we offer based on a 24” monitor.

The table shows how each lens has different magnification level ranges. Which microscope and which lens you should choose depends on your object and what magnification levels you need.

 

 

Lens ZAP ZIP TREND PRESTIGE
Lens +2 0.8x – 26x
Lens +3 1.3x – 40x 1.3x – 40x
Lens +4 1.7x – 53x 1.7x – 53x 1.7x – 53x 1.7x – 53x
Lens +5 2.2x – 66x 2.2x – 66x 2.2x – 66x
Lens +10 4.3x – 133x 4.3x – 133x 4.3x – 133x
Lens +25 11x – 330x 11x – 330x
Lens +50 21x – 660x
