Today’s one of the very invaluable tool for research and education is the microscope. In a wide range of scientific fields, where major discoveries in biology, medicine and materials research; microscopes are now being used. Optical microscope, the first to invent and most common kinds of instrument containing one or more lenses that produces an enlarged image of an object visible in the focal plane of the lens(es)
Compound microscope as an optical system magnified real images produced by a lens or lens system, which is called “the objective”, and is further enlarge by eyepiece then finally enlarged and the final form of a virtual image for user’s eye observation.
Using digital cameras for photo microscopy provides an exciting means of capturing and flaunting the world that is not known through an ordinary naked eye. Photographs captured through a microscope are also known as photomicrograph. Through a digital camera attached to a compound microscope, these photographs were documented. Two advantages that a digital technology can offer, an apt feedback and a multiple inexpensive pictures. With the difficulties associated in capturing good images from millimeters size objects, these aspects are important
Bugscope helps teachers to integrate in a classroom set up activity microscopic view of minute objects. The atomic force microscope, invented by Binnig Quate and Gerber in 1986, is a very powerful microscope that aside from imaging is one of the significant tools in manipulating matter at the nanoscale. In pathology practice, the array of microscope change. Capturing images known as virtual slides enable pathologist to go digital following the lead of radiology decade ago. While widefield microscope, thick specimens will create an image that acts for the sum of sharp image specifically from the in-focus region combined with blurred images from all of the regions that are out of focus. The most widely used in both industrial and fundamental research to obtain atomic-scale images of metal surfaces is the scanning tunneling microscope (STM). Presents the three-dimensional profile of the surface that is very helpful in determining the size and conformation of molecules, characterizing surface roughness, observing surface defects, and aggregates on the surface. Latest innovation is a robotic microscope incorporated through a personal computer to control mechanical motion and video imaging. These tools allows an on screen viewing of an object and complete control over imaging, focus, magnifying and XY pixels stage movement. Through this, enlargement of captured image on screen made picture measurement more convenient and an alive true color images through a video for storing and retrieval is now made possible.
These microscopes can reach and magnify 200 times or more of more exciting vivid microscopic images. Its creation and development provides, ease of use, satisfaction and a great sense of accomplishment to the scientist. It is also an amazing experience to amateurs in the field of experiments in preparing samples to observe and in the creation of permanent slides to project using a computer. A very interesting laboratory experience for teachers if each of his or her students having their own small microscope that while doing an experiment activity he or she will be able to introduce the fundamental concepts of optics and scientific research. .
