A microfiche is a single sheet of plastic that contains several images of pages of text, whereas microfilm is a long spool of plastic film that winds and rewinds to view images of text. In both instances, these microforms require a projection system whereby images of microfiche and microfilm appear on a backlit screen to be viewed.Know More
Microfiche is usually 6 inches by 4 inches per sheet. Users place microfiche under a plate of glass. Once under the glass, light shines behind or beneath the plastic microfiche while a lens increases the image size. The image from the lens is then projected onto a small screen so individuals can read the text.
Microfilm is viewed in much the same way, only spools move microfilm back and forth under the plate of glass similar to a spool of movie celluloid. Microfilm holds many more document images than a single sheet of microfiche. Technology has improved to allow microfilm and microfiche images to be viewed on digital computer screens using special programs.
