    • PROBLEM TO BE SOLVED: To provide a simple type vacuum zip-fastener bag capable of preventing ingress of air during the evacuation from the vacuum zip-fastener bag and before sealing after evacuation, and an aid therefor.
      SOLUTION: An outwardly directed second zip-fastener member is provided in a vicinity of a mouth part of a zip-fastener bag, an auxiliary tool having a third zip-fastener member to be attachable/detachable to/from the second zip-fastener member is connected, and after air is discharged from the aid side, a first zip-fastener member provided on an inner side of the mouth part of the zip-fastener bag is sealed. Since the zip-fastener bag and the aid body are connected to each other by the zip-fastener member, air is discharged while maintaining an airtightness of both members to tightly seal the zip-fastener bag, and no air enters during the intake or the tightly sealing. The zip-fastener bag can be sealed while air is sufficiently discharged.

    • A beam splitter having an optical multilayer thin film is disclosed. The optical multilayer thin film is formed by laminating six layers in sequence. The laminated six layers comprise: a first layer, a third layer and a fifth layer each having a refractive index from 1.63 to 1.64; a second layer and a sixth layer each having a refractive index from 1.37 to 1.38, a fourth layer having a refractive index from 1.9 to 2.3; in which light is allowed to be incident upon the first layer of the optical multilayer thin film at the angle of incidence equal to or greater than 40.degree.. The reflectances of S and P polarized components of reflected light are substantially equal to each other over a wide wavelength range and substantially no phase difference exists between the S and P polarized components. The beam splitter having a multilayer polarizing light separating film formed between an incoming side prism and an outgoing side prism is extremely high in the reflectance of the P polarized component of reflected light, in comparison with that of the S polarized component of the same reflected light.
    • 公开了一种具有光学多层薄膜的分束器。 光学多层薄膜依次层叠6层。 层压六层包括:折射率为1.63-1.64的第一层,第三层和第五层; 第二层和第六层,每层具有1.37至1.38的折射率,第四层的折射率为1.9至2.3; 其中允许光以入射角等于或大于40°入射到光学多层薄膜的第一层上。 反射光的S和P偏振分量的反射率在宽波长范围内基本上彼此相等,并且在S和P偏振分量之间基本上没有相位差。 与入射侧棱镜和出射侧棱镜之间形成的多层偏振光分离膜的分束器相比,反射光的P偏振分量的反射率相对于相同反射光的S偏振分量的反射率非常高 。
