Manufacturing is the mainstay of the real economy, and the importance of manufacturing is being emphasized globally. Scanning electron microscope (SEM) as a powerful analytical instrument, will have a great role in improving manufacturing product innovation and product quality.   However, in practice, there are often concerns that the SEM is easily damaged, complicated to use, and takes a long time to get started, resulting in high hidden costs.   CIQTEK SEM R&D team to address this pain point, with the goal of "everyone can use" to create an "easy but not simple" tungsten filament SEM2000.  CIQTEK tungsten filament scanning electron microscope SEM2000     Easy But Not Simple   SEM2000 operation interface is simple, easy to get started, durable, low failure rate and even beginners can easily use it. SEM2000's high degree of automation, key imaging, automatic focus, automatic dispersion, and automatic contrast function, greatly simplify the steps of debugging parameters. SEM2000 has a complete anti-collision process, which can completely avoid the sample from touching the objective lens polar shoe, secondary electronic detector, and other parts.   Below are pictures taken by a beginner using SEM2000 after a short training period. Clear image, good contrast, and a large depth of field.      If you want to reduce the cost of use and increase the efficiency of operation.If you have never used an electron microscope before and want to try SEM for the first time.If you want the tool to be simpler.Then SEM2000 will be your best choice!     

Tungsten filament Scanning Electron Microscopy (SEM) is cost-effective, easy to maintain, relatively simple to operate, and requires less space, making it easy to use by the general public. However, for a long time, the resolution of tungsten filament SEM has been at a standstill, making it difficult to achieve the user's pursuit of higher resolution.   CIQTEK recently introduced the SEM3300, a tungsten filament scanning electron microscope that has successfully increased its 20 kV resolution to 2.5 nm, a 16% improvement over ordinary tungsten filament electron microscopes!3 kV resolution of 4 nm, a 2-fold improvement!1 kV resolution of 5 nm, a 3-fold improvement!  It redefines the industry standard of tungsten filament scanning electron microscopy by significantly outperforming ordinary tungsten filament electron microscopy in all voltage bands!   CIQTEK SEM3300   The following three pictures are real pictures of standard gold particles at different voltages, each particle size is around 300nm, with sharp edges, rich details, and distinct heights.    Images of standard gold particles at different voltages taken with SEM3300    It is well known that the diaphragm material in lithium batteries has poor electrical conductivity and tiny pores, and a low-voltage, high-resolution field emission electron microscope must be used to capture better images. Figure a shows the effect of conventional tungsten filament SEM, the details are blurred and unclear. SEM3300 accomplishes this difficult task effortlessly, the septum pores are clearly visible at 1 kV, and the edges of the pores are sharp enough for septum inspection (Figure b).    Figure a: Lithium battery septum photographed by conventional tungsten filament SEM, with blurred and unclear details    Figure b: SEM3300 photographed lithium battery diaphragm, diaphragm pores clearly visible, the sharp edge of the hole     How the CIQTEK SEM3300 is redefining tungsten filament SEM?   The CIQTEK SEM R&D team analyzed the main factors limiting the resolution of tungsten filament SEM: The tungsten filament emission structure is a 3-electrode structure with a cathode, gate, and anode. At low acceleration voltage, the filament brightness will be significantly reduced by the space charge effect and electron source aberration. At low landing energy, the chromatic and diffraction aberrations caused by energy dispersion are large, resulting in a large beam spot. In order to ensure the collection efficiency of the lateral secondary electron detector, the working distance is relatively large and the objective magnification is not large enough.   In response to these problems, CIQTEK added a 10 kV high voltage tube from the anode directly to the objective lens pole shoe inside the mirror barrel, which we figuratively call a high voltage tunnel. Here is an example of 1 kV landing energy.     At the upper end of the high-volta...
