Abstract: A measurement end of an optical fiber is passed through a through hole of a holder. While the optical fiber is being rotated by using the through hole as a guide, output light from the measurement end is received by light receiving means.

Abstract: A method for manufacturing a GRIN lens includes the steps of forming a wet gel provided with a concentration distribution having a different concentration of a refractive index distribution imparting metal that differs in concentration in a radial direction, drying the wet gel to form a dry gel having a bulk specific gravity ? (g/cm3), sintering the dry gel to form a GRIN lens base material and stretching the GRIN lens base material while heating. The method is characterized in that, in the step of sintering the dry gel, partial pressures of oxygen during sintering at 800° C. or higher are 10?1 Pa or lower and also the relation between a rate of temperature increase v (° C./hr) and a bulk density ? of the dry gel during sintering at 1,000 to 1,150° C. is defined by v?105*EXP (?12?). As a result of this, the GRIN lens, which has a large numerical aperture and a small diameter, can stably and easily be manufactured.

Abstract: An antiallergen filter of the present invention is characterized in that a water-insoluble high-molecular weight anti-allergenic agent having a phenolic hydroxyl group and a moisture-absorbing material are carried on a filter. Because of using the water-insoluble high-molecular weight substance as an anti-allergenic agent, the antiallergen filter of the present invention is free from a problem that the anti-allergenic agent flows and drops or is detached from the filter due to moisture in the atmosphere, etc. even in a highly humid environment or the like. Further, since the moisture-absorbing material is carried on the filter, moisture that the anti-allergenic agent requires for adsorbing and capturing an allergen and inactivating its allergic activity can be effectively retained on the filter. Thus, the antiallergen filter of the present invention can effectively exert its anti-allergenic effect over a prolonged period of time.

Abstract: An optical fiber coupling part that reduces the difficulty in adjusting cores, minimizes coupling loss, and prevents optical characteristics from deteriorating. An optical fiber is fused to one end of a GRIN lens which includes a quartz glass containing one or more refractive index regulating substances selected from Sb2O3, Ta2O5, TiO2 or ZrO2. Optical characteristics are not deteriorated because an adhesive is not used, and self-alignment effects facilitate adjustment of the cores of the GRIN lens and the optical fiber. Furthemore, coupling loss can be minimized by setting a refractive index distribution constant g of the GRIN lens within an appropriate range.
