Electron microscopes and stereomicroscopes each carry their own unique benefits and drawbacks. Understanding the specific characteristics of each type is important to use them flexibly.


In general, if expressed in English, both can be called “microscopes”. Although in industry there are instances when microscopes are referred to as microscopes, in this case we will explain “microscopes” in terms of single-eyehole digital display machines.

 1. Difference in Characteristics

・Features of Physical Optical Microscopy:

One big difference is that the Entity Optical Microscope is designed with two independent optical systems, creating two independent light paths on the right and left.




When observing with a physical Optical Microscope, the viewing range from right and left will be different. If you place a coin as follows to observe:






When observing, the observer will see both different visions as a single image, similar to how humans have two eyes.


The benefit of this is that the object will look like a real space. You can also understand the feeling of near and far, so people doing processing work often need to use Physical Optical Microscopy. The downside is that it requires a bit of technique when using (first-time users may feel strange about the unnatural image).


In the case of a Trinocular Optical Microscope, the camera port will contain an image from one side, either the right or left side (the image will also have a tilt effect).


Another disadvantage is the inability to observe at high magnification (due to the need for delicate adjustment between the right and left sides during manufacturing). The magnification is usually low and the magnification ratio is not large. Normally, even for general types, magnification is only 10 to 50 times, and in high-end cases, only about 100 times is the limit of physical Optical Microscopy.


Furthermore, in long-term work, workers can experience a lot of pressure. Eye widening, vision correction, and personal adjustments by the observer are necessary.


Because the field of vision is different between right and left, it is not suitable for precise positioning and two-dimensional measurement. In the above applications, people often use monocular microscopes.





・Features of Microscope:

Basically, it mainly uses single lens.



Just like when people look at objects with one eye, this has the disadvantage of making it difficult to perceive near and far. In the case of the coin mentioned above, when viewed from the center of the lens, the image will look like this:




Because it is possible to choose from a variety of lenses, the microscope can accommodate from low to high magnification (exceeding 2000x).


Furthermore, with on-screen observation, even new users can easily observe without causing fatigue, suitable for long-term observation (inspection).

Due to the frontal view (upward angle), it is also suitable for locating and measuring dimensions. It is compatible with computers and can use a variety of software such as image storage, image processing, focus fusion, and many other features.


2. Difference in Magnification

Magnification between Physical Optical Microscopy and Microscopy cannot be directly compared. While Optical Microscopy is visually confirmed, Microscopy is observed on a screen.


At that time, the magnification of the screen must be taken into account.

Although a direct comparison of magnification is not possible, if the comparison is based on the field of observation, a simple difference can be seen.


For example, the field of view of a microscope is calculated by the number of fields. For a microscope with 20 fields, when magnified to 10 times, the field of view will have a diameter of 20 mm.



If one wants to observe the same field as in the mentioned physical Optical Microscopy, with the Microscope below, the magnification will be 20 times.


(Meanwhile, in Organic Optical Microscopy, the magnification is only 10 times.)



Furthermore, in the case of a Microscope, the magnification will vary according to the screen size.


For details, see the article below.


3. Differences in Primary Applications

・Physical Optical Microscopy is suitable for applications such as:

Installation, machining, physical object inspection/observation, etc.


・The microscope is suitable for applications such as:
Check appearance, determine precise positioning (such as shaft placement), measure dimensions without surface deviation, etc.
