Generally speaking, microscopes can be classified into two basic types. And these two are the low power microscopes and the high power microscopes. A high power microscope, as its name suggests, are microscopes that are capable of magnifying their specimens to as much as 1000x or even more. Low power microscopes, on the other hand, can only do so at around 40x, although there are also some brands that provides for 80x magnification.
And so by this description alone, it can clearly be seen that high power microscopes are better off viewing very small samples like cells, tissues, and microorganisms. Low power microscopes, on the other hand, are best used for viewing slightly bigger objects like insects, stamps, and coins.
Also, low power microscopes use transmitted and reflected light for its lighting system. This allows users to view almost all types of objects with it, whether it is transparent or opaque. Low power microscopes are stereomicroscopes. They are capable of producing three-dimensional images of the specimen they would like to see.
More often than not, the 3D images produced by low power microscopes help their respective users a lot as far as viewing images with full accuracy are concerned. On the other hand, high power microscopes are not able to produce 3D images at all. Aside from the fact that most of them are monocular microscopes, high power microscopes lights their samples not in the same as was low power microscopes. And as far as creating 3D images are concerned, lighting plays a very crucial role.
For watch repair, circuit board inspection, and similar applications, low power microscopes are the ones used. It is impossible to repair a watch or a circuit board using high power microscope. This is because the microscope would magnify the small parts of the watch too much, making repairmen miss the damaged part altogether. They are better off using low power microscopes that magnifies the sample just right so that they can see the whole mechanism through the eyepiece, without the need to constantly move the specimen just so it can be viewed fully.
Aside from this, a high power microscope can only provide a maximum working distance of 2mm. When repairing watches, it is important that the repairman is able to manipulate the sample while he was working on it. This feat is nearly impossible with a high power microscope. If you move the sample away from the objective, then you will lose sight of it altogether. Therefore, you won’t be able to do the necessary repairs it need.
Low power microscopes are better and that is because they provide for as much as 100mm working distance. This distance allows users to easily maneuver the watch they have at hand, move it as they like, take out parts, and replace then with new ones. All these they can do with full ease and efficiency.
One other thing that makes low power microscope perfect for watch repair is the fact that these microscopes are usually equipped with zoom objectives. The main job of these objectives is to zoom in and out of the sample seamlessly. This is very helpful with watch repair and similar applications. Sometimes, it is necessary for repair men to look through a particular spot in the watch there are repairing. Zooming into the specimen would allow the repairman to see whether there are scratches and physical deformities in the watch that they are trying to repair. By zooming into the particular area, they can decide right there and then if the part needs to be replaced or not.
To make low power microscopes fully workable for watch repair, these microscopes have to be mounted, preferably on a boom stand. Boom stands allows users to move the microscope’s lenses directly below the working area. So instead of the sample following the microscope’s lenses, it works the other way around. The articulating arm of a boom stand low power microscope can be moved in such a way it is directly focused on the delicate watch that has to be repaired.
Right now, there are different low power microscopes available in the market today. But not all of them are specifically created for watch repair, although they can be used for this particular purpose just fine. So if you are going to buy low power microscopes for watch repair, always make sure that the full manipulation of both the sample and the objective lenses of the microscope can easily be achieved. This ensures you that the microscope you will buy is fully functional with the application you are going to use it for.
