The same specimen holder can now be used for both the optical microscope and the scanning electron microscope. As a result, by managing the stage information with dedicated software, it is possible for the system to record the locations observed with the optical microscope, and then further magnify the same areas with the scanning electron microscope to observe the fine structures at higher magnification & higher resolution.The observation targets found with the optical microscope can be seamlessly observed with the scanning electron microscope without having to search for the target again. It is now possible to smoothly and easily compare and verify the optical microscope images and scanning electron microscope images.
