Used RAITH 150 #293662702 for sale

RAITH 150 is a scanning electron microscope (SEM) that is composed of two primary components: the electron gun and the specimen sample. The electron gun serves to generate electrons, which are then directed onto the sample. The sample is then scanned and observed by the component of the system referred to as the imaging column, which holds the internal lenses that focus the electrons onto the sample. The output of the imaging column is then examined by the observer in real time. The electron gun in 150 is composed of a heated tungsten (W) filament that is located within an Escaped beam Column (EBC) and is encapsulated within a vacuum environment. The temperature of this W filament is then heated to the point at which electrons are generated and escaped from the filament at an accelerated velocity. Once these electrons leave the W filament, they are then accelerated forward in the imaging column. The imaging column in RAITH 150 is composed of electrostatic lenses of which are inserted into various stainless steel grid holders. These lenses focus the accelerated electrons onto the specimen sample. These lenses are adjusted in order to maximize the resolution that the lens can provide to the sample. The image is then acquired and visualized by the video camera and image processing software which is located on the system. The specimen sample in 150 can be composed of a wide variety of materials ranging from light organic compounds to heavy metals. The sample is mounted onto a stage which is moved relative to the imaging column in order to observe different areas of detail. Prior to mounting, samples are first prepared via a physical or chemical etching process. In conclusion, RAITH 150 is a highly advanced scanning electron microscope that is composed of two primary components: the electron gun and the specimen sample. The electron gun produces the electrons that are then accelerated on to the sample and the imaging column focuses the electrons onto the sample, generating a real time image. This image can then be visualized by the video camera and the image processor software. With its large range of sample materials and degrees of resolution, 150 is the perfect tool for advanced electron microscopy.
