    摘要： Light processing apparatus (20) comprises a piezoelectric high polymeric film (1) supported under tension at least at two opposite ends (2, 3) thereof, at least one pair (8 or 9) of electrodes arranged to produce an electric field (E) across the thickness of the polymeric film and optical means (19) connected to the polymeric film such that said optical means can be displaced upon piezoelectric response of the film to a voltage applied across the electrode. The optical means may be a mirror or a lens fixed to the polymericfilm. The apparatus can be used to control accurately, for example, the angle through which a light beam is reflected.

    摘要： A lens material having a refractive index n 20 D of at least 1.57 and an Abbe's number v of at least 30, comprising: a copolymer comprising (I) 10 to 85% by weight of a halogen-containing monomer represented by the following formula (1), (II) 15to 90% by weight of a halogen-containing monomer represented by the following formula (2), and (III) 0 to 20% by weight of a monomer copolymerizable with the above mentioned monomers, the composition of the copolymer being based on the total quantity of the monomers (I), (II), and (III):
    wherein: D represents
    in which n represents an integer selected from the group consisting of 0, 1 and 2; each R' represents hydrogen or a methyl group; Y represents CHOH; and r represents 0 or 1; each of X' and X 2 represents, independently from each other, a methyl group in which one through three of the hydrogen atoms are substituted by a member selected from the group consisting of bromine, iodine and a hydroxyl group (OH group), with the proviso that the number of substitution of the OH group is only one; X 3 represents a methyl group in which one through three of the hydrogen atoms are substituted by a member selected from the group consisting of bromine, iodine and D, with the proviso that the number of substitution of D is only one; wherein at least one of X', X 2 , and X 3 contains at least one bromine or iodine;
    wherein: each R 2 represents hydrogen or a methyl group: p represents an integer selected from the group consisting of 0. 1. 2. and 3; X 4 represents bromine or iodine; and q represents an integer selected from the group consisting of 1, 2.3.4. and 5.
    An example of the copolymer is 1-methacryloxy-2,2-di (bromomethyl)-3-bromopropane. methacryloxypolyethyoxy-2.4.6- tribromobenzene styrene divinylbenzene having a n 20 D of 1.596 and a v of 3 5 .3.
