When scientific research is done, precision is important in any type of analysis. Traditional microscopes are considered relatively primitive optical tools. However, they still provide accurate methods of observing specimens that would not be visible with the unaided eye. Microscopes have zooming capabilities that are on scale of a few hundred times in magnification. Modern cutting edge digital technology has significantly improved optics that are used for scientific purposes. These days, it is no longer necessary to lean over and look into an eyepiece of a microscope that stands on a table. Contemporary video measurements systems use advanced optical lenses and mirrors to provide magnified images that are crystal clear. The images of a microscopic slide are shown in great detail on a display unit such as TV or computer monitor.
Precision in microscopic measurement is very important. Digital remote controls allow scientists and technicians to accurately control the movement of lenses that zoom in and out on a specimen. In fact, electric motorized arms are used to precisely move the lenses up, down, left or right. There is no reason to use manual knobs to move around objective lenses.
Contemporary video measurement systems might also use advanced laser and other electromagnetic technology. For example, an outline of a microscopic specimen can be mapped by projecting laser beams onto the surface. Such methods can be used to estimate dimensions that are on a nanoscale, which is much smaller than subjects studied under traditional microscopes. The evolution of digital and optical technology has led to the development of the nanotechnology industry. The high tech future is all about taking advantage of living things and man made items on an atomic scale. At the same time, small items that are visible with the naked eye can still be analyzed with precise tools.
For example, it would be difficult to measure small items with traditional calipers. Sometimes, technicians need to know the thickness of something that is less than a millimeter. Precise video measuring systems can zoom in onto subjects and create virtual dimensions that are superimposed on the display screen. For example, a clear millimeter scale can be generated on the video of a specimen. Best of all, video based measurements can be imported into a computer and shared with other users instantly. It is possible to share with others an in depth analysis of specimens by using a single optical device.
