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.

The brachial plexus can contain fibers from?
C4 - t2
What does fibroblasts secretes?
Fibroblasts produce three types of connective tissue fibers: collagenousfibers, elastic fibers, and reticular fibers. Of these, collagenousand elastic fibers are the most abundant.
Does the ventral ramus contain only motor fibers?
True
What branch of the spinal nerve contain autonomic fibers?
The rami communications
How many types of fibers are there?
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.)
Are HCS optical fibers smaller than glass optical fibers?
false!
When were optical fibers first made?
1856
What is inside optical fibers?
Mirrored glass
What has the author Hiroshi Murata written?
Hiroshi Murata has written: 'Handbook of optical fibers and cables' -- subject(s): Optical fibers, Handbooks, manuals
Can electricity be transmitted through optical fibers?
No. Light is transmitted through optical fibers.
What technologies are optical fibers used with?
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.
How do tools that implement optical fibers improve medical care?
Tools with optical fibers improve medical care by allowing physicians to see inaccessible places
How light can be used for communication?
using optical fibers....
Is optical fiber hollow or not?
Yhere are varirties of Optical fibers with different sizes and characterstics but all of them are solids.
What is the maximum voltage and current optical fiber can take?
Optical fibers transmit light, not electrical energy.
What do fibers contain?
Most Fibers contain starch.I hope this helps :)Regards Bushy.
What optical fibers made of?
High purity glass strands.
