Pellicle

From Camerapedia.org

A pellicle mirror is a piece of glass covered with a very thin film, making it semi-transparent. It is used as a fixed mirror in some SLR models, the first one being the Canon Pellix in 1965. This system helps in reducing mirror slap vibrations, and the finder is not blackened during the exposure. But the amount of light going to the viewfinder is less than with the traditional mobile mirror. Later the pellicle mirror was mainly used on special high speed cameras that could take many pictures per second (usually more than 5), on which the moving mirror meant significant time wastage, and a continuous vision of the subject while firing was appreciable.
