Compact, Easy to Use, Expandable TEM


Compact, Easy to Use, Expandable TEM JEM-120i

Transmission Electron Microscopes (TEM) of 120kV accelerating voltage are widely used in soft material fields such as biology and polymer. We developed the JEM-120i with the concept of "Compact", "Easy To Use", and "Expandable". With the new external appearance, this instrument has evolved into a useful tool that anyone can use easily, from operation to maintenance.

Key Features



JEM-120i drastic reduction in size
The instrument has an LED light on its front and its color changes depending on the state of the TEM. You can determine its operating state at a distance.
With the drastic reduction in size, the JEM-120i has a filament replacing position and specimen holder insertion position lower than existing instruments. A newly developed cartridge type filament unit helps make filament replacement easy and safe for anyone.

Easy to Use

Easy to Use

It takes only 4 steps from loading a specimen to completing observation. After inserting the specimen holder, clicking the Start Button automatically performs observation preparation operations such as voltage increase and emission start. A wide area image is captured at the same time. So, clicking the target field will move the stage to the clicked position.
Since standard "Butler mode" assists data acquisition, even a beginner can capture data easily. When observation completes, you can exchange the sample holder while keeping the emission on.

Specimen observation in 4 steps

Seamless observation without switching magnification mode

The JEM-120i is equipped with an enhanced TEM control system and fully automated apertures, eliminating the need for switching magnification modes and selecting an aperture. Observation operations can be performed more smoothly than with previous models.


The JEM -120i supports a variety of retrofits. It also meets the need for additional functions after purchase.
