WebA stereo microscope works on the reflected light from the sample. The magnification of the microscope takes place at low power and hence, it is suitable for magnifying opaque objects. It is suitable for thick and solid samples because it uses light reflected from the sample. The magnification of the stereo microscope is between 20x and 50x. WebLow-pressure electron microscopes are commercially available that can work at normal air pressure or increased pressures. Because the sample is imaged with electrons, rather than with photons in optical microscopy, no color information about the sample is communicated and images are presented in grayscale. hana villa nova
