Abstract: A liquid crystal filter made of a plurality of region having different liquid crystal molecule arrangement directions has a problem that linear defects, which are visible at boundaries between different liquid crystal molecule arrangement directions, are captured by image capturing elements. Therefore, provided is a liquid crystal filter comprising a first region that includes liquid crystals arranged in a first direction; a second region that includes liquid crystals arranged in a second direction, which is different from the first direction; and a buffer region that is disposed between the first region and the second region, and includes liquid crystals arranged in an intermediate direction between the first direction and the second direction.

Abstract: Provided is a method for manufacturing polarized glass, comprising forming a glass preform by melting glass that includes metal ions and halogen ions and then depositing metal halide particles in the glass in which the metal ions and the halogen ions are dispersed; forming a glass sheet containing extended metal halide particles that are obtained by extending the metal halide particles by performing thermal drawing on the glass preform at a prescribed temperature; annealing by heating the glass sheet to a temperature that is no greater than a transformation temperature of the glass and no less than a distortion temperature of the glass; and reducing the extended metal halide particles in the glass sheet that has undergone said annealing into extended metal particles. The glass preform formed in said forming a glass preform has a haze between 0.3% and 1.3% with respect to light in a wavelength region passed by a G filter.

The core glass does not contain germanium. Glass fiber having this core-cladding structure is mechanically strong and exhibits only small transmission loss of infrared light passing through the fiber.

Abstract: A process for producing a preform for a chalcogenide glass fiber which comprises inserting a cladding tube having contained therein a chalcogenide glass rod for core into a quartz tube having at its bottom a nozzle having an aperture smaller than the outer diameter of the cladding tube, locally heating the bottom of the quartz tube and pulling the cladding tube having contained the glass rod for core and a process for producing a chalcogenide glass fiber by heating and drawing the preform thus obtained, by which processes the devitrification of glass and the generation of bubbles in the core glass or at the core glass-cladding glass interface can be prevented and the adhesion between the core glass and the cladding glass can be improved. In particular, when the glass material for core does not contain Ge, a chalcogenide glass fiber having such a core-cladding structure that the transmission loss of the glass fiber when infrared light pass through the fiber is small and the mechanical strength is high.

Abstract: A process for producing a chalcogenide glass fiber which comprises placing a cylindrical chalcogenide glass preform vertically in a cylindrical crucible furnished with a nozzle in its bottom portion, heating the crucible only at vicinity of the nozzle, and continuously drawing the glass into a fiber with the temperature of the crucible at the vicinity of the nozzle being maintained at such a level that the viscosity of the glass is within the range of 10.sup.3 to 10.sup.7.5 poises.
