With over 30 years of experience, we are your expert partner for high-quality fiber optic cables and sensor technology. At our location in Aßlar, we develop and manufacture customized solutions – from prototypes to large-scale production. Whether for laser technology, microscopy, or industrial process control: We guarantee the highest precision according to ISO 9001 and offer flexible adaptations for demanding environments.

Many Terms / for the Same Technology

We use this terminology:

  • Optical fiber = raw fiber
  • Fiber optic bundle = component of the fiber optic cable
  • Fiber optic cable = light transmission cable

For over 30 years, we have been developing, manufacturing and assembling fiber optic cables in Aßlar from a wide variety of glass, quartz and plastic optical fibers for applications in optoelectronic sensor technology, laser technology and microscope illumination – in direct dialogue with our OEM customers. In addition, we manufacture coiled fiber optic bundles and extruded fiber optic cables in endless lengths, which our customers assemble themselves.

As experts in the field of development, manufacture and distribution of fiber optic components, we offer our customers special developments and prototypes in the shortest possible time, as well as larger series production according to the DIN ISO 9001 quality standard.

Sensor Fiber Optic Cables / from Synova

Fiber optic sensors are special transducers for optical measuring methods. The basis is the use of optical fibers as a medium for signal transmission of light, usually in the infrared wavelength range. The measuring methods work without contact, and the change in various parameters of the light used is evaluated. These include, above all, the intensity, wavelength (color) and polarization, as well as the transit time of the signals.

Due to the fiber-specific advantages such as small dimensions, low weight, no electrical or magnetic components and resistance to external electromagnetic influences (EMC), fiber optic sensors can be used universally.

Application

Diverse applications of intrinsic and extrinsic sensors

Sensors / intrinsic

Optical fibers are transducers and thus both sensors and the line for signal transmission. Examples are:

  • fiber optic pressure sensors
  • fiber optic strain sensors

In these sensors, the change in the optical fibers, for example due to pressure or tension, is accompanied by a change in transmission or a shift in wavelength, which is ultimately evaluated by the receiver electronics.ng der Transmission oder Verschiebung der Wellenlänge, die letztendlich durch die Empfängerelektronik ausgewertet wird.

Sensors / extrinsic

Here, the optical fiber merely serves as a transmitter of the measured variable detected by the sensor, which must be available as an optical signal. Examples are:

  • fiber optic temperature sensors (pyrometers)
  • fiber optic light barriers

In these sensors, states are detected by transmitter and receiver electronics, e.g. in high-temperature applications or in automation technology.  

Application / industrial

You can achieve advantages through fiber optic technology in these areas:

  • Automation technology: process control
  • Industrial process control: transmission and reflection light guides
  • Detection of smallest objects
  • High-temperature applications: steelworks, coking plants
  • Explosive environments
  • Fire protection: flame monitoring
  • Temperature measurement with pyrometers
  • Liquids, chemicals: level measurement, leak detection
  • Industrial lighting: illumination of critical process areas
  • Microscopy: single/multi-arm gooseneck or ring light guides
  • Laser technology: fiber optic beam guidance systems for high-power lasers in material processing
