3.5 Extending Human Vision

Microscopes• A compound light microscope uses two convex lenses to magnify small, close objects. Magnify means to make the image look larger than the real size.

• To focus the image, the object is moved closer to or farther away from the object lens. Adjusting the distance to make the image clear is called focussing. See pages 216 - 217

Refracting Telescopes

• A refracting telescope has a convex lens to collect and focus light from a distant object, and a convex eyepiece lens to magnify the image.

• Problems with refracting telescopes include: Large objective lenses flex, due to their own weight and distort the image.

Glass lenses, even of the highest quality, absorb some of the light and are expensive.

• A reflecting telescope uses a concave mirror, a plane mirror, and a convex lens. Light enters the telescope and is focused after reflecting off the concave mirror.

A plane mirror reflects the light towards the eyepiece.

The convex lens in the eyepiece magnifies the image.

• Most large telescopes are reflecting telescopes.

• Binoculars are actually two refracting telescopes mounted side by side.

• To shorten the length of the tubes in binoculars, prisms are used to reflect the light back and forth.
