Microscope range from the simple single lens with sophisticated microscopes with imaging systems. The different microscope on the basis of their resolution, magnification, lighting methods, image type, the field of view, degree of automation, etc.
Depending on the source of radiation, the ‘optical microscope’ (also known as ‘กล้องจุลทรรศน์แสง’ in the Thai language can be broadly classified as light, electron and confocal.
Light microscopy utilizing visible light as the radiation source. The compound microscope gives a 2- dimensional view of objects that can be used for the purpose of the laboratory.
Phase-contrast microscopy and dark field microscopy to modify the principles of light microscopy to improve the visual quality of the specimen.
Oil immersion microscope using oil between the lens and the specimen to increase the magnification.
Scanning probe microscopy is a microscope group, which forms an image. scanning probe microscopes mainly include scanning tunneling microscopy, atomic force microscopes, near-field scanning optical microscope, etc.
It has great application in nanotechnology. By the magnetic force microscope, microwave, acoustic, etc. are also available. Microscope inference used with perfectly transparent objects that are not visible under an ordinary microscope.
