GRIN technology
high-precision gradient optics
“made in Jena”

Unique technology from Jena
GRINTECH is a global leader in the development and manufacture of gradient index lenses (GRIN lenses for short) and micro-optical systems. This technology is based on a continuously changing refractive index in the material, which precisely deflects light beams and enables the miniaturization of optical systems.
Compared to traditional lenses, where the light is refracted at the curved surface, GRIN lenses with their flat surfaces offer a much more flexible and cost-effective solution with simplified geometry and without complex surface shapes.
Using an innovative, non-toxic silver and lithium ion exchange process in special glasses, GRINTECH produces GRIN lenses with diameters ranging from 0.2 mm to 2 millimeters, which are used in numerous applications such as microscopy, medical technology, the semiconductor industry, mechanical engineering and research. These lenses not only offer excellent optical properties, but also a high degree of flexibility to adapt the focal length and working distance to specific requirements.

Precision and miniaturization for the most demanding applications
GRINTECH has decades of expertise in the production of diffraction-limited GRIN lenses with high imaging quality. The company is the only supplier in the world to manufacture these lenses using an environmentally friendly and biocompatible process based on silver and lithium ion exchange. In contrast to the conventional production of GRIN lenses using thallium ion exchange, this unique GRINTECH key technology is non-toxic and therefore poses no health or environmental risks for manufacturers or users.
GRIN lenses are characterized by their special optical quality and offer maximum precision in compact systems. They are used in areas such as cell research, neuroscience, medical imaging and optical inspection and measurement systems, thus contributing to the further development of technologies in various industries.
With a broad portfolio of micro-optics and complete system solutions, including complex optical assemblies such as miniature microscopes, fiber-optic, non-contact measuring sensors, micro-objectives, laser lines or spectroscopic probes, GRINTECH is an innovative partner for international customers in research, development and industry.
