Supply, installation and commissioning of Benchtop Scanning Electron Microscope with EDX microanalyses SPECIFICATIONS: 1. Electron Optical System 1.1 Electron gun: Tungsten hairpin filament type. The filament should be able to replace by the user, does not require a dedicated service engineer. 1.2 Accelerating voltage: variable from 5 kV to 15 kV in at least 3 steps. 1.3 Magnification range: variable from at least x10 to x100,000 times or more while maintaining the same resolution in the mentioned range. 1.4 condenser lens : electromagnetic 2-stage zoom condenser lens system. 1.5 Automatic alignment, focusing, astigmatism and brightness/contrast correction built-in. 2. Specimen Chamber 2.1 specimen size :80mm (diameter) x 50mm (height) and more. 2.2 travel range in the X and Y directions: at least 40mm and 40mm. 2.3 CCD camera: Preferably of the same brand as the SEM and it should be built-in the top of airlock chamber. The captured image by CCD should be utilized in order to specify the measurement point on the Graphic User Interface (GUI) as navigation function linked to stage movement. This system should have a function when we zoom up from the CCD image, it will continue seamlessly to the SEM image. 3. Vacuum System: fully automatic system 3.1 The microscope must be support both high vacuum and low vacuum capability. 3.2 The vacuum mode can be selected from GUI or the evacuation mode button of the main unit. When switching between high...
