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.

Cooperation as key to joint success

Grid

We place great value on trusting and long-term customer relationships. For us, transparency is the cornerstone for successful and lasting cooperation and joint growth.

One example of this is our partnership with Inscopix, a leading company with products for the neurosciences. This cooperation is representative of the close collaboration with our OEM partners. Inscopix uses our high-precision lenses for miniature microscopy in the field of neuroscience. Our products are an integral part of their devices used to visualize neurons in vivo. With the help of our technology, researchers can understand how nerve cells communicate with each other. For our partner, it is clear that the quality of GRINTECH lenses is crucial for excellent imaging in neuroscience.

We have also been working closely, trustingly and very cooperatively with Micro-Epsilon, a leading international supplier of industrial sensors, for a long time. Our lenses are used in high-precision, non-contact distance measurement sensors. Customized solutions with GRIN lenses play a key role for precise measurement and control in Micro-Epsilon’s reliable and high-quality products.

Biocompatibility

Sustainable & biocompatible

Grid

Our GRIN lenses are manufactured using a non-toxic silver and lithium ion exchange process in special glasses. They have been successfully tested for full biocompatibility and medical use according to the EN ISO 10993-1 standard, Directive 93/42/EEC.

This makes GRINTECH the only company in the world that manufactures gradient index optics based on non-toxic and biocompatible silver and lithium oxide exchange processes. We are thus making an important contribution to the world of tomorrow.
