Abstract
An optical transmitting system comprising a light source, an optical transmitting portion from the light source, and an optical detecting portion characterized in that a fraction of deuterium substitution for hydrogen in a repeat unit of an organic polymer composing the optical transmitting portion is at most 40%, fluorine content in said organic polymer is less than 40% by weight, and said organic polymer comprises an amorphous polymer which satisfies the equation (I): EQU (.rho./M)(9.1.times.10.sup.-5.n.sub.CH +9.1.times.10.sup.-4.n.sub.NH +1.5.times.10.sup.-3.n.sub.OH)<5.3.times.10.sup.-6 (I) [where, .rho. is density of the polymer (g/cm.sup.3), M is molecular weight of the repeat unit (g/mol), n.sub.CH, n.sub.NH, and n.sub.OH indicates number of combination of C--H bond, N--H bond, and O--H bond in the repeat unit respectively].
