Method, system, and equipment for glass material processing as a function of crystal state

A system for glass material processing, comprising:

• glass material comprising glass that may form crystals;
• a hot stage heated by heating elements at least partially surrounding the glass, wherein at least some of the glass is at a temperature of at least 500° C.;
• a light source that provides light at a wavelength λ that interacts with the crystals that may be form in the glass, wherein at least 95% of light energy from light of the light source is within a 5 nm band around wavelength λ thereby facilitating spectral contributions of shifted spectral bands of crystalline states of the glass material, while mitigating effects on the glass material due to wavelength-induced changes to the glass material caused by the light;
• a wavelength separator that separates out a spectrum δ of light from the glass that is within a range of (λ−20 nm) to (λ+20 nm);
• a detector that is set to receive light of the spectrum δ of light from the wavelength separator;
• optics that guide and/or focus light from the light source to the glass in the hot stage, and that collect and/or guide light directed from the glass in the hot stage and direct the light directed from the glass to the wavelength separator, wherein the optics at least in part prevent the detector from receiving light at the wavelength λ, thereby focusing the detector on nano-scale shifted light within the spectrum δ;
• and
• a computerized controller, where the computerized controller is in electronic communication with the heating elements of the hot stage and facilitates a control loop between the heating elements and the detector where the computerized controller changes conditions in the hot stage as a function of information derived from the detector such that at least some of the glass in the hot stage is at a temperature within 400° C. of a melting temperature of the glass.
