Laser scanning microscopes |
– Use laser light– Scan object point by point– Construct an image of it on the computer using pixel information– Images = high-res, high contrast– Depth selectivity– Use for whole living specimens and cells |

Scanning electron |
Electrons do not pass through the specimen– Electron been because secondary electrons to bounce off specimen surface– Focused on to a onto the screen– 3D image– Magnification times 15×200,000 resolution 2.05– Greyscale colour and in computers and false colour imaging– Specimen coated in fine film metal and put into vacuum |
