<p>825-2, also known as conductively cooled cold cathode electron gun, is a device used in electron microscopy. It consists of aheater, a filament, an anode and a grounded shield. It is similar to 850-2 in its shape but has a heater and filament at the end of the gun instead of the brush at the entrance of the gun. The gun is often used in conjunction with a field emission gun and operated at higher voltages to provide higher resolution images.</p><p>The working principle of 825-2 is based on the fact that electrons are emitted from a metal surface when heated. The electrons released are accelerated towards the anode and a beam of electrons can be obtained. The cathode is heated by an electric current, which causes the electrons to be emitted in the form of a beam. The beam is then focused and directed towards the sample to be analyzed.</p><p>The 825-2 is often used in fields such as high resolution microscopy, micro fabrication, and electron beam lithography. It can be used for producing images with resolutions up to 10 nanometers. It is also widely used in the analysis of materials and structures, as well as in electron diffraction. Its high resolution makes it a valuable tool for research and for commercial uses.</p><p>The 825-2 electron gun is also used in scanning electron microscopy (SEM). In this application, an area of the sample is scanned with the electron beam in order to create an image. This technique is used to observe the surface of objects in detail and to analyze their composition. The 825-2 gun produces focused electron beams and thus has excellent resolution and contrast in SEM images.</p><p>The 825-2 electron gun is also used in analytical electron microscopy (AEM). In this application, the sample is scanned with an electron beam and the energy of the beam is analyzed. This technique is used to determine the composition of the sample and the nature of its surface. The 825-2 gun provides excellent resolution and contrast in analytical electron microscopy.</p><p>The 825-2 electron gun is a powerful tool for investigating the structure and composition of materials and for its applications in electron microscopy. Its high resolution, contrast, and analytical capabilities make it an invaluable tool for research and for commercial use.</p>The specific data is subject to PDF, and the above content is for reference
