    摘要: A panoramic imaging lens having an annular light incident surface formed in a substantial convex lens form; a first reflective surface formed in an annular concave mirror form to reflect light inside the lens; a second reflective surface provided at a central part inside the annular light incident surface to reflect the reflected light from the first reflective surface toward an inner part of the annular first reflective surface; and a light outgoing surface positioned at a central part inside the annular first reflective surface and opposing the second reflective surface to transmit light. A non-reflective part exerting no regular reflection of light is provided on a light path toward the light incident surface amongst light paths of light proceeding to agree with a light path of imaging light incident on and refracted at the light incident surface and proceeding inside the lens.

    摘要: A packing material for chromatographic use which comprises an inorganic carrier having hydroxyl groups at the surface thereof having grafted thereon an .alpha.-arylalkylamine derivative which is formed by bonding an optically active .alpha.-arylalkylamine and an aminoalkylsilane through a dibasic carboxylic acid, and a method for liquid chromatographic analysis of an enantiomer mixture using this packing material as a stationary phase. The packing material of the present invention can be easily produced by the usual chemical reaction, is chemically stable, and exhibits excellent effects in the separation of an enantiomer mixture of a compound having an --NH-- group, --CONH-- group, or an --OCO-- group bonded to an asymmetric carbon atom thereof.
