Abstract

PURPOSE:To enable transmission of infrared rays of up to long wavelength by constituting a main part by using glass made up of a germanium oxide and antimony oxide or germanium oxide, antimony oxide and other glass components. CONSTITUTION:With regard to optical fiber 1 for infrared-ray transmission having the main part of core 2 and clad 3, germanium oxide-antimony oxide glass is used as the constituent substance of the glass constituting the main part and the composition mixture of each part is carried out so that core 2 has a high refractive index and clad 3 has a low refractive index. Further, other components are allowed to coexist within the limit that optical fiber 1 never deteriorates in characteristics. Such a constitution can reduce a scattering loss of the glass remarkably and also transmit infrared rays of long wavelength well.
