Damage analysis of glass and silicon

Glass and silicon


We clarify fracture formation, fracture patterns and causes of damage through damage analysis of layers and complete assemblies that were damaged or broken during production or use. These include:

Float glass

Laminated safety glass

Tempered glass

Semi-tempered glass

Technical glass (measuring cuvettes)

Quartz glass

Domestic glass

Glass ceramics

Automotive glazing

Architectural glazing

We also perform load tests on components in the laboratory as required for damage analysis.


Benefits for our customers


We determine the causes and provide evidence for fracture patterns, formation mechanisms, stresses, possible unforeseen circumstances, loads, overload, material defects, and preliminary damage.

You thus obtain clarity on the causes and can take targeted remedial measures, such as changing materials, changing the glass production and finishing processes, reduction of stress or adjusting or altering the design or dimensions.

You also receive information on adjustments in the manufacturing processes and improvements to the mechanical resistance of the products, as well as on cost savings in production.

We work with you to perform studies to improve process steps in order to lower the loss ratio and minimize the risk of the occurrence of damage. In special cases, we make use of numerical simulation methods for optimization.

Silicon components damage analysis services


Damage, strength and process analyses similar to those used for glass. We include product-specific manufacturing steps in the analysis.

Examples of components:


Solar cells

Solar panels

Optical lenses (e.g. IR lenses)

Microsystems technology and precision components

Examples of production steps:

Machining processes (sawing, sanding, polishing)

Chemical milling







Application also for other crystalline optical materials like germanium, calcium fluoride or zinc sulfide.
