Electron microscope how much

For one thing, the microscope needs to be isolated from the environment, and so the facility must have a system for canceling magnetic fields. Better yet, it should be located underground.

What determines the price of an electron microscope? What are other costs associated with electron microscopes? What type of electron microscope should you buy? Before moving to purchase any SEM, new or used, the first couple of questions that must be answered are:. Besides asking about your timing and budget, one of the first topics that any SEM technical sales engineer will ask about is your application.

By knowing your particular application, the engineer should be able to intelligently refine your search to focus on a particular type of SEM. The choices essentially come down to emitter type and detectors used to collect the electrons as they are reflected back off the sample. There are three basic types of emitters, or sources used for electron emission: field emission FE , tungsten W , and lanthanum hexaboride LaB 6.

The three methods of detecting these electrons are a standard Everhart-Thornley E-T detector, an upper detector, or a backscattered electron BSE detector. Today, for high-end nanotechnology applications, such as viewing individual carbon nanotubes or advanced semiconductor devices, field emission SEMs with an upper detector are required, as shown in Figure 1.

In addition, while tungsten or LaB 6 SEMs may appear in Figure 1 to approach the resolution of the FE-SEMs, they need to view the sample at higher accelerating voltages, which means that samples must be coated with a thin metallic layer. Since FE-SEMs can image at very low accelerating voltages, the need to coat samples with a metallic layer is substantially reduced. However, it is at the expense of lower resolution. Generally speaking, various applications have different resolution requirements, and this reality prompts the need to consider SEM type.

The resolution a scanning electron microscope can provide at low-accelerating voltages is the major determinant of its selling price. View Complete Details.

Depending on how many customizations and the complexity of them they can really start to add up. Some examples of customizations are:. Another factor that affects the cost of electron microscopes is sample accommodation. Depending on the type of specimens being observed there may be special requirements regarding weight, size, ventilation, or barriers required to accommodate the specimen. Depending on the requirements for specimen accommodation this can dictate either customizations to the electron microscope or picking a different electron microscope altogether.

Some high resolution electron microscopes can resolve images at around 0. There are specific objective lens and imaging systems that are required to achieve these high levels of resolution and they are not cheap. High end electron microscopes will have low kilovolt specifications that allow high resolution on specimens that are beam sensitive. There are many different components that can contribute to price differences among electron microscopes, but the majority of variation can come from these components:.

Beyond the obvious cost considerations of buying an electron microscope, careful consideration should be paid to a few other aspects that can affect your decision. Electron microscopes are extremely expensive and require months of planning and consideration before a purchase can be made. In this article you have seen some examples of used electron microscope prices to give you a sense of what some electron microscopes can be resold at as well as the estimated costs that they were originally sold at.

I hope with the examples provided and some of the things that should be taken into consideration before purchase, you will be equipped with the knowledge needed to proceed forward in your important purchase.
