Mirror sites are often located in a different geographic region than the original, or upstream site. The purpose of mirrors is to reduce network traffic, improve access speed, ensure availability of the original site for technical [2] or political reasons, [3] or provide a real-time backup of the original site.
The pellicle mirror causes an up to 1/3-stop loss of light at the receptor, and a corresponding 2-stop loss of light in the viewfinder; The mirror has to be kept perfectly clean, or the light sensor and other electronics (as well as the image quality) will suffer. Owing to its thinness, the pellicle mirror is fragile, making it difficult to clean.
A cross-section (or 'side-view') of the optical components of a typical SLR camera shows how the light passes through the lens assembly, is reflected by the mirror placed at a 45-degree angle, and is projected on the matte focusing screen.
