How it works. . .
To observe close images, a microscope has to first refract the diverging lines coming from the object into parallel lines. This first refraction hapens in the objective lens to direct it towards the eyepiece lens. Int he eyepice and the objective lense there are two lenses. This is due to the fact that different colors of light refract diferently, the second lens helps correct the error. A typical microscope has one plano-convex lens at the opening and the three otehrs are bi-convex lenses. By multiplying the magnification of the objective and the eyepiece you get the total magnification.
Parts of a microscope
Eyepiece lens- manification about1 10X, used to view specimen.
Arm- to carry microscope and to connect base and top part
Base- to support specimens
Light- to adjust the brightness of the specimen
Focuses- used to make the image clear with small or big adjustments
Objective lenses- amplify from 40X to 1000X
The first microscope!
Zacharias Janssen created the first compund microscope in 1595. His microscope had two convex lenses but the objective was flat on one side. The invented microscope had 9 times more power than the earlier ones.
A microscope is an apparatus used to magnifythe tissues of animals and plants. It is similar to telescope but its able to focus the light in objects that are close.
