Thermo-optical investigations in transmitted light

The microstructure and optical transmittance thermal analysis of sodium borosilicate bio-glasses

“…3) because of the diffusive light (scattering) reflexion on phase boundaries. The preliminary experiments to this respect were made using optical transmittance measurements [8][9][10] during isothermal glass sample treatment at temperatures 700, 720 and 740 °C. Here in Fig 4, the ordinate axis means the transmitted light intensity expressed in arbitrary units.…”

“…Optical transmittance measurements were accomplished using an instrument described elsewhere [8][9][10]. The "white" light emitting diode (LED) was used as a light source.…”

Computed optical transmission records: An effect of dense-medium phase function as an approximate description of multiple light scattering

“…(2)(3)(4). It is usually convenient to relate the number concentration of scattering particles with the degree of conversion (or degree of crystallinity) α.…”

“…The attenuation of a light beam incident perpendicularly to a glass slab was expressed in terms of the optical transmission (OT). Stepwise computation of the light scattering efficiency as a function of the crystal size yielded continual data sets corresponding, in a specific way, to the time dependent OT thermal records [3,4].…”

Light scattering simulations relevant to crystallization of lithiumdisilicate glass

“…In our former work we tentatively measured the loss of glass transparency in the course of lithiumdisilicate glass crystallization [1]. A real-time optical transmission method (further referred to as the OT method) has been employed for this purpose [2].…”
