Abstract: PROBLEM TO BE SOLVED: To easily distinguish polarizing glass with different polarization axes without any mark on the polarizing glass such as a scratch.SOLUTION: The spectral reflectance curves of polarizing glass surfaces in the visible light region are configured to be different in accordance with the directions of polarization axes of the polarizing glass. Accordingly, when the polarizing glass is illuminated and visually observed, color tones look different in accordance with the polarization axes, and thereby difference in the polarization axes can be distinguished by the difference in color tones.

Abstract: PROBLEM TO BE SOLVED: To provide a polarizing element composed of a metal particulate-dispersed type polarizing glass in which isolation of ≥30 dB can be attained even in a pigtail type optical isolator.
SOLUTION: A method for obtaining the condition of reduction is disclosed by which a polarizing element produced by reducing a glass substrate in which the acicular particles of silver halide or of first copper are dispersed so as to be oriented to one direction in a reducing atmosphere, thus forming a reduction layer comprising acicular metal silver or copper exhibits an extinction ratio suitable to be used in a pigtail type optical isolator. For each of samples of the polarizing elements obtained by reducing the test samples of a glass substrate under at least two reduction conditions, the distance to a light receiver is set within 100 mm, an extinction ratio is measured with light having a wavelength of 1.3 to 1.6 μm, the polarizing element sample in which the extinction ratio is the maximum or the highest is selected, and a reduction condition under which the selected polarizing element is prepared is determined as reduction condition under which an extinction ratio suitable for a pigtail type light isolator is exhibited. Also a method for producing a polarizing element under the reduction condition obtained by the above method, the polarizing element and an optical isolator are disclosed.
