The Annealing Process for Glass Material

The annealing process is critical to the durability of glass. Among the variety of issues for improperly annealed glass is the probability of the glass to crack or shatter from just a slight temperature change. When glass is not annealed correctly, the thermal stress can significantly decrease the overall strength of the glass. The Annealing Point and Heat Soaking Annealing…

Witness Samples

Witness samples are exactly as their name implies—samples of optical materials and/or coatings. Companies use witness samples as “witnesses” to a coating run in the thin film coating process. Witness samples allow testing without handling the actual part, to ensure the coating process is accurate before moving forward with the optical component. When testing, witness samples are often used to…
