[Homer-users] Optical Fibres suggestions

[Dennis Hueber]

Just a note concerning the ISS instruments and fibers. 200 to 400 micron 
core is best for the sources, because the coupling of the lasers into 
the fiber may be a problem. Also, very small bundles have been used. The 
efficiency is not as good but is consistence. If you are building your 
own instrument and you want to use much smaller and flexible single 
fibers. You could get the lasers coupled by Oz-Optics and use 50 or 62.5 
mircon fiber, which as just about as flexible as single-mode. We have 
done this with prototypes.

About NIRS retransmission. Just about any optical-fiber will work in 
short lengths (a few feet). If you want long fibers pay attention the 
spectrum supplied by the manufacturer. Some transmit NIR better than 
others.
