Electron microscopes
An electron microscope is a microscope that uses electrons instead of light to magnify objects that are being observed, as opposed to optical microscopes that use light to magnify objects.
Electron microscopes are widely used in various fields such as physics, chemistry, engineering, biology and medicine.
For more than half a century, Daiwa Techno Systems, Inc. have contributed to the development of the industry by manufacturing parts that are the heart of electron microscopes, and providing them to manufacturers of analyzers and other analytical equipment worldwide.
Parts machined by Daiwa based on schematic diagrams of the structure of scanning electron microscopes
There are two main types of electron microscopes: scanning electron microscopes (SEM) and transmission electron microscopes (TEM).
A scanning electron microscope (SEM) is a device used to observe the surface of samples by applying an electron beam to the sample and detecting electrons emitted from the sample surface.
Main products machined by Daiwa
- Electron guns that generate electron beams
- Focusing apertures that narrowing the electron beam
- Objective apertures for adjusting the electronic gun opening angle and probe current
- Scintillators for measuring secondary electrons emitted from samples being observed
- Sample stands for keeping samples stable
