SLR Camera Digital Lenses can comprise a number of components. Complex Camera Digital Lenses may have over 20. The most common material used in SLR Camera Digital Lenses is glass, mainly due to its good optical properties as well as its resistance to scratching. Quartz glass, ,fluorite and various forms of plastic are also used in some camer digital lenses.
The use of plastics in some SLR Camera Digital Lenses, allow the manufacture of highly aspherical lens elements which are almost impossible to create using glass. Plastics in SLR Camera Digital Lenses can improve lens manufacture process and the overall performance quality. While plastic is often used on inner elements, they are only used on the outermost elements of all but the cheapest lenses as they scratch easily.
An indication of their utility is that molded plastic lenses are used in the manufacture of the cheapest throw-away disposable cameras. manufacturers of quality optics tend to use euphemisms such as “optical resin”. While it is true that glass provides for higher quality performance than plastic in SLR Camera Digital Lenses, many modern and high performance lenses from big brand labels include some molded or hybrid aspherical elements.
