Formerly, endoscope optics consisted of a series of thin converging "relay lenses", creating a succession of images in the air spaces between them. Following the innovation by Harold H Hopkins, the thin lenses in air were replaced by thin air lenses in glass. In other words, each lens consisted of a rod, with convex polished surfaces at each end. This increased the light throughput, and avoided the metal spacer rings needed in the old design. Some endoscopes instead use bundles of fiber optics to convey the image, which renders them flexible.

Fibroblasts produce three types of connective tissue fibers: collagenousfibers, elastic fibers, and reticular fibers. Of these, collagenousand elastic fibers are the most abundant.
True

There are two basic types of optical fiber.Multi Mode Optical FiberUsed to transmit many signals per fiber. (Multi Mode fibers are generally used for computer networks, lan applications).MultiMode Optical Fiber is produced as 50/125 and 62.5/125. (Core/Cladding diameter in microns.)Single Mode Optical FiberUsed to transmit one signal per fiber (Single Mode fibers are generally used for telephone and cable tv applications.)Single Mode Optical Fiber is produced as 8/125 and 9/125. (Core/Cladding diameter in microns.)

No. Light is transmitted through optical fibers.
Optical fibers are flexible transparent fibers made of glass or plastic and transmits light between its two ends. They are mainly used in the fields of applied science and engineering.
Tools with optical fibers improve medical care by allowing physicians to see inaccessible places
using optical fibers....
Yhere are varirties of Optical fibers with different sizes and characterstics but all of them are solids.
Optical fibers transmit light, not electrical energy.
Most Fibers contain starch.I hope this helps :)Regards Bushy.
