A broad spectrum

of top-level, high-tech products

High standards
in materials and precision

Kyburz Sapphire works for international clients from all sectors of high-tech industry. What they all have in common are high standards for materials, and processing precision. Thanks to our many years of experience, we are in a position to deal with clients’ individual needs. We can thus develop innovative, effective solutions for you, even in areas that are new to us.

Medical technology

Biocompatible, impervious in contact with tissue and fluids, and easy to sterilise: sapphire is an ideal material for applications in human and veterinary medicine, such as cover glasses for endoscopy and camera systems, or light conductors for technological dental instruments used in diagnosis and treatment. Thanks to our prototyping, we can guarantee the swift production of test series. Since June 2020, we have had our own equipment for producing and testing micro-lenses. Our processing and measurement technology is suited to the series production of lenses from r 0.7 mm to r 7.0 mm.

High-performance optics

We produce components from ultra-hard materials for high-performance optical uses in high-tech industry, such as flat optics, mirrors, wedge windows, fibre optics and spherical lenses. Standards are continually becoming more demanding, which means sophisticated production engineering is needed to ensure flatness, surface finish and the purity of the materials, especially when making optics suitable for laser applications.

Analytical technology

Increasing demands in the analysis of processes and products in high-tech industries require well-founded expertise in the characteristics of sapphire material, also with regard to its purity and crystal orientation. This is why you can completely rely on our sapphire optics for measuring systems such as refractometers, spectrometers, photometers and pyrometers.

Aerospace technology

Of this we are especially proud: we have succeeded in developing a procedure that enables the production of sapphire windows of considerable size. Flat and spherical sapphire windows serve to protect optical sensors, camera systems and infrared measuring devices. Our components meet the highest standards regarding form and durability in the face of environmental influences.

Mechanical engineering

For industrial applications, we produce wear-resistant components from sintered ceramics or carbide metals. These components include bearing rings, ultrasound welding moulds, isolators for high-voltage engineering and guiding elements. In all these fields, precision and durability are our prime quality criteria.


In scientific research, custom-made products are often required, such as:

  • Precision substrates and optics for space projects
  • Sapphire windows for high-pressure applications in deep-sea conditions
  • Sapphire components for vacuum measurement cells in fusion reactors
  • Unique, customised parts for research projects at universities
  • Special parts for student projects at universities
