Light microscope
1) conventional optical microscopes are used.
The lens consists of two types of objective lens and eyepiece. The light passing through the lens to the object, and then visualize the object clearly
2) stereo camera-based lighting.
The camera includes a lens that makes use of 3D objects is large, but the naked eye can not distinguish details. This type of camera is different from a typical camera is
1. The image is a virtual image with depth and a three-dimensional image
with a low magnification objective lens 2 is less than 1
3. the use of translucent objects. and an opaque object
4. Distance from the objective lens to the object in the range of 63-225 mm
2. electron microscope. This requires special preparation and some with an extra 2) electron transfer indiscriminately (Scanning electron microscope) referred to as SEM M. Denny Vaughan end successfully built since 2481 using the skin cell. the surface of the object to be studied. SEM's electron beam to the surface. This makes images look three-dimensional images, the work of an electron microscope wheels. Use of the camera lens as a light, but to make a magnetic field at high magnification. You can illuminate objects up to 0.5 nm, making it appear realistic. Plastered on the screen glow
