When using a roughness meter or contact profiler to measure a surface, there is a risk of damaging the surface of the object, particularly if the material is soft. Additionally, it is impossible to accurately measure any changes in the surface that are smaller than the tip of the stylus.
Since laser microscopes perform non-contact scanning of a surface, there is no damage done to even soft objects. Also, with a laser beam diameter that is significantly smaller than a stylus tip, these systems can collect much more accurate data of the surface.
Besides the scanning process, laser microscopes also make it much easier to actually measure. Instead of having to place the stylus in the proper location to collect data, laser microscopes can quickly scan an entire area and measurements can be done at any location on the screen.
Imaging with a scanning electron microscope (SEM) has the advantages of higher magnification and resolution than that of an optical microscope.
However, SEMs are not able to provide color information and require pre-processing of the samples, which can take a significant amount of time.
Laser microscopes can provide color images at magnifications up to 28,000x with no need for sample preparation or a vacuum. These systems are much faster and easier to operate, yet still allow users to obtain high-resolution images.
The VK-X Series employs an industry-leading 16-bit photomultiplier (PMT) as its light receiving element.
This high-resolution PMT is able to capture incredibly accurate surface data even on steep angles or complex shapes. While typical laser-based systems struggle at low magnifications, the VK-X Series easily collects data over a wide area or on materials with large changes in contrast.
The measurement results of the VK-X Series 3D Laser Scanning Confocal Microscope are based on a traceability system linked to national standards. The accuracy and repeatability of this series is guaranteed, which means users will always get reliable measurement results.
Additionally, on-site verification can be performed as needed to ensure optimal performance.
