Studies on the light-focusing plastic rod. 14: GRIN rod of CR-39-trifluoroethyl methacrylate copolymer by a vapor-phase transfer process.
The gel rod, partially polymerized CR-39 [diethylene glycol-bis-(allyl carbonate)], is placed in the atmosphere of trifluoroethyl methacrylate (3FMA) vapor, followed by heat-treatment to yield the GRIN rod. Examining the relationship between the preparation conditions and the optical properties of the GRIN rod, the plastic GRIN rods with a quadratic-index distribution up to their periphery and with higher than 0.36 N.A. were fabricated.
