Used AMRAY 1830 #9314144 for sale

AMRAY 1830 scanning electron microscope is a high-resolution imaging tool for exploring the structure and composition of microscopic objects at the nanoscale level. It operates by taking a series of two-dimensional images of a sample from multiple angles, that is then combined into a three-dimensional representation. AMRAY design employs a detection system that utilizes an electron beam rather than traditional optical light sources, allowing for higher levels of resolution. The electron source consists of a filament made of tungsten, which, when heated, emits electrons. The electrons are accelerated by an anode and then passed through a Wehnelt cap which is adjustable to optimize the focus of the electron beam. The acceleration voltage range of the electron gun is 0 - 30 kV and the sample is positioned within the sample chamber against a ground plane. The electrons interact with the sample, either being reflected or scattered. The scattering of high-energy electrons produces secondary electrons, which are then detected by a detector located outside the sample chamber. 1830 utilizes a secondary electron detector. The secondary electrons are detected by a Faraday cup, which produces an electrical signal proportional to the number of electrons that strike the metal cup. This signal is then amplified by an amplifier connected to the Faraday cup. Additionally, AMRAY 1830 includes a user-friendly graphical user-interface (GUI) with a variety of settings for adjusting parameters, such as operating voltage, signal sensitivity, and image resolution. 1830 is capable of producing images with a resolution of up to 5 nm. This makes it an excellent tool for studying a variety of materials and objects, including semiconductors, biological samples, rocks and minerals, and more. The images generated by AMRAY 1830 can be used to analyze composition, morphology, and elemental composition to provide detailed insight into a sample. 1830 is a reliable and powerful tool for conducting high-resolution imaging at the nanoscale. With a resolution of 5 nm, it has applications in a variety of industries, including semiconductor, medical device, and materials research.
