WebThe ray diagram in the picture shows 3 'rays' of light entering the telescope. Each ray hits … WebLight microscope diagram. Light microscopes magnify objects by using two biconcave lenses that manipulate the light falling into the lenses, making them appear bigger. The light is manipulated by a series of glass lenses that will focus the beam of light onto or through a specific object. Fig. 1 - The different parts of a light microscope. WebThe situation in the reflected-light microscope is different. Here, the ray path is folded about the axis of the specimen where light is reflected from its surface. The objective acts as its own condenser, and the alignment of the reflected-light microscope is very much simplified (see the ray diagrams in part 2 of this series). bamboo dinner set camping
