Information

In recent years, there has been a graphene whirlwind in the world, and more and more enterprises and scientific research units have begun to focus on the preparation and testing of graphene materials. It is particularly important to detect the morphology and structure of graphene. We found that three-dimensional confocal The microscope is not only used to observe the three-dimensional morphology and morphology of the sample surface at the sub-μm level, but also to measure a variety of tiny dimensions, such as volume, area, grain, film thickness, depth, length and width, line roughness, surface roughness, etc. Wait. Moreover, the test is convenient and quick, without damaging the sample, and it is more applicable than scanning electron microscope and atomic force microscope in actual use. Several experts from the national-level Taizhou Graphene Research and Detection Torch Platform pointed out that 3D confocal microscopy can easily detect graphene transferred through PMMA (to detect PMMA residues), graphene transferred through PET, and the 3D morphology of copper-based graphene, etc. , etc., has begun a wide range of effective applications in the field of graphene.
The 3D confocal microscope of Juna Group has complete functions, compact structure, high cost performance, ultra-high optical resolution and the most comprehensive and extensive 3D surface topography analysis capability, and has become the first choice of many domestic graphene users. The device adopts the patented multi-hole confocal technology, combined with the image capture of CCD, replaces the holes of the detector with a rotating disk with many holes, and then moves the objective lens vertically, similar to tomography, in a short time (about a few seconds) Accurately measure the three-dimensional data of the object. The measurement method is non-contact non-destructive characterization, which will not damage the surface of the sample. It does not require measurement in a vacuum environment and pre-preparation of the sample. The measurement can be completed in only 5 to 10 seconds; the measurement function of the microscope can also be used to observe the sample. , it can also be used normally in harsh working environment. Due to the use of the confocal method, when measuring the height of a large gradient, compared with other methods, the height of the object can be measured more accurately and a 3D stereo image can be established, which has obvious advantages.
