engionic Fiber Optics GmbH has been designing and manufacturing tailor-made fiber optic light guide solutions and fiber optic sensors for more than three decades. The customer-specific products are used, among other things, in power plant monitoring, medical technology and industrial process monitoring.

The added value for the customers of engionic Fiber Optics lies in the consistent support, starting with the development of the prototypes, to the start-up of the series production and then to the continuous optimization of the products and the manufacturing costs.

engionic Fiber Optics, thanks to its many years of experience, has been perfectly aligned to the needs of industrial customers who integrate the fiber optic components into their overall solutions. Product traceability, quality management and delivery reliability are part of the corporate DNA.

engionic Fiber Optics GmbH is part of the engionic Group.


The engionic group of companies focusses on the development and production of OEM specific products and components and covers the entire product life cycle, from prototyping to volume production. The group‘s technological focus lies on the design and production of fiber optic components and sensors, as well as the production of high quality precision CNC parts.


In 2022, we rebranded the engionic Group companies to create a joint brand identity. Loptek GmbH is now engionic Fiber Optics GmbH, FemtoFiberTec GmbH is now engionic Femto Gratings GmbH and KIESSIG CNC-Zerspanung GmbH is now engionic CNC GmbH. Each company operates as an independent entity, while we maximize the synergies between the group companies to provide the best value proposition to our customers.


Within the group, engionic AG fulfills the function of a strategic investment holding company. All share holdings are bundled in this company. The main purpose of the holding company is the active further development of the business portfolio through organic growth and the selective acquisition of further businesses, as well as the identification of new technologies and products that are evolving on the market and can be scaled to industrial levels.


engionic AG is a family business and privately owned.


engionic Femto Gratings GmbH
engionic Femto Gratings GmbH is the world's first commercial manufacturer of fiber Bragg grating (FBG) sensors based on a very complex fs-Laser inscription process. Our products have strong technological unique selling point over conventional fiber Bragg grating sensors, especially with regard to demanding environmental conditions, such as very high temperatures and pressures, as well as radioactive radiation.

Within the engionic Group, engionic Femto Gratings GmbH supplies its sister company engionic Fiber Optics GmbH with FBG sensors, which are then further processed into assembled sensor solutions.

engionic CNC GmbH
engionic CNC GmbH is looking back on more than 20 years of experience. The tailor-made components are manufactured from a wide range of materials and at an exceptionally high level of precision and quality, which is particularly appreciated by medical technology customers.

Within the engionic Group, engionic CNC GmbH also manufactures precision components for engionic Fiber Optics GmbH, which are installed in light guides and sensor applications.
