Grintech GmbH

Grintech GmbH is a medium-sized high-tech company based in Jena, Germany — the city known as the "Lichtstadt" (city of light) — with roughly 25 years of innovation experience in micro-optics. The company specializes in GRIN (gradient-index) micro-optics made of glass, and on the basis of these "Gradient Index Lenses" it produces highly precise miniaturized optical components and systems with unique properties. Its technology is described by the company as globally unique and as revolutionizing the way light can be used in various applications. Grintech's core competence spans research, development and production of custom precision optics. Its rod lenses and cylinder lenses are manufactured through a unique, non-toxic silver ion exchange process in glass. The resulting micro-optics can be as small as 250 µm, and down to 125 µm when required, offer simple coupling to planar surfaces, and allow precise mounting with other components. The company emphasizes sustainability and biocompatibility, achieved by avoiding toxic materials. The company's products serve demanding applications in fields such as sensor technology, fiber optics, biophotonics, medical imaging, telecommunications and laser diode beam shaping. Its interdisciplinary team brings decades of experience in physics, engineering, precision optics, chemistry and industrial mechanics, and works continuously on new, individual solutions for the most demanding requirements. Grintech is headquartered in Jena, Germany, and operates as a private company. It markets its micro-optics technology and custom precision optics to customers worldwide, positioning itself as a partner for innovative micro-optics solutions.

Grintech GmbH is a medium-sized high-tech company headquartered in Jena, Germany, a city traditionally known as the "Lichtstadt" (city of light) because of its long optical-industry heritage. According to the company's own description, it has around 25 years of innovation experience in micro-optics. The company was founded to develop and manufacture GRIN (gradient-index) micro-optics from glass, and it has built its business on the resulting "Gradient Index Lenses" and on highly precise miniaturized optical components and systems. Grintech's technological foundation is a unique, non-toxic silver ion exchange process in glass, used to produce its rod lenses and cylinder lenses. This process allows the company to create micro-optics with very small dimensions — down to 250 µm, and to 125 µm when required — that can be easily coupled to planar surfaces and precisely mounted with other components. The company emphasizes that its technology is globally unique and that its products are sustainable and biocompatible because they avoid toxic materials. Over the years, Grintech has developed strengths in research, development and production, enabling it to realize holistic solutions for individual precision optics. Its interdisciplinary team combines decades of experience in physics, engineering, precision optics, chemistry and industrial mechanics. The company serves a wide range of application fields, including sensor technology, fiber optics, biophotonics, medical imaging, telecommunications and laser diode beam shaping. Grintech remains an active private company based in Jena, Germany, marketing its micro-optics technology and custom precision optics to customers worldwide.
