Glass laser cutting for demanding applications in industry and high-tech

Glass is one of the most versatile materials in modern industry. In addition to its high transparency, it offers impressive chemical resistance, electrical insulation properties, and high thermal shock resistance. Today, technical glass is used in numerous high-tech applications—from optics and photonics to microelectronics and medical technology. For the production of complex components and ultra-fine structures, precise laser processing offers the highest accuracy while minimizing material stress.

What is glass?

Glass is an amorphous, non-crystalline material that can be shaped at elevated temperatures. It is characterized by its high transparency, good chemical resistance, and low electrical conductivity. At the same time, glass possesses high hardness and excellent thermal shock resistance. 

Technical glasses are specialized types of glass that have been developed for specific industrial and technical applications due to their unique properties and compositions. However, because of its brittle structure, precise glass processing places special demands on the manufacturing process.

Glass is used, among other things, in:

  • optical components
  • microelectronics
  • sensor technology
  • medical technology
  • display and photonics systems
