“…This is because the internal refractive index distribution of the glass does not change when locally subjected to stress or heat, so the retardation is retained. Colorless transparent oxide glasses with small photoelasticity can be used in the visible region, 2),3), 5) whereas chalcogenide glasses are used in the infrared region due to their high transmittance. 6), 7) The PEC in glass depends on the probe wavelength and composition.…”

The photoelastic constant (PEC) of a square-shaped glass, such as very tough and fragile glasses of a mechanical nature and a very small stress-induced birefringent glass, can be successfully obtained by a heterodyne method. The merit is that the PECs can be obtained even for difficult compositions to re-form into disk-shaped, instead of the commonly used method of measuring PECs with disk-shaped glass. The PECs of square and disk-shaped glasses with the same composition can be obtained within «0.2 © 10 ¹12 Pa ¹1 measurement accuracy. This phenomenon could be developed into a potential glass that can be processed into square shapes with high precision but is difficult to process into disks using glass lenses and filters.
