Technica Optical Components

World leader in premium grade fiber Bragg gratings. High quality components reliably used in hundreds of applications worldwide.

Contract manufacturing begins with a fiber Bragg grating made by Technica. Then, our company makes its portfolio of its in-house state-of-the-art technologies available for building on and around the FBG to meet the customer’s specific requirements. Whether the FBG is to be built-up into a custom array, into a special cable sensor, into a packaged strain, temperature, pressure, angle, displacement, or other type of sensor, or into an optical communications cassette together with other optical devices according to our customers' designs, we are well prepared to manufacture!

Premium quality fiber Bragg gratings and FBG arrays for customized sensors, polyimide-coated sensors to 300 °C, gold-coated hermetically sealed sensors, small-diameter FBGs, radiation hard/proof sensors, tilted FBGs, and high-temperature FBG sensors to 1000 °C. We also produce FBG matched pairs for fiber lasers and athermal FBG wavelength references.

The process begins with a fiber Bragg grating or FBG array made by Technica. We then package the fiber(s) into specialized cables such as Armor (T110), GFRP (T130), Steel (T140), PEEK/TEFLON (T150), Gold (T160). We also package multiple FBG arrays within the the same cable in length ranges far beyond standard available technologies.

Premium quality fiber Bragg grating sensors and FBG array sensors in acrylate, polyimide, and gold coated fibers, specialized polyimide-coated sensors to 300 °C, high-T FBG sensors to 1,000 °C, radiation hard/proof sensors, bio-chem tilted FBG sensors and ultra-thin FBG sensors and arrays. We produce GFRP FBG cable sensors for embedding into concrete and other materials, Zeus PEEK FBG cable sensors for monitoring in transformers and chemically active environments, and vibration-sensitive cable sensors for security.

The T420 is a single-mode fiber (SM) based fiber Bragg grating (FBG) based packaged displacement sensor for use in environments from -20°C to +60°C, packaged to eliminate influences from the ambient environment. Ready for direct mounting steel construction exhibiting excellent wavelength to displacement linearity.

World leader in Fiber Bragg grating and Fabry Perot filters. Product portfolio includes athermal Fabry–Perot etalons (TWR30) and athermal FBGs (TWR50), as well as tunable FBGs (T10-T980) and tunable Fabry–Perot filters (TFP10-TFP50).

The T620 is a high-accuracy and sensitivity single-mode fiber (SM) based Fiber Bragg Grating (FBG) based packaged pore water pressure sensor for operation to 150 psi.

Available in a wide range of optical specifications. Packaged with two internal FBGs to eliminate influences from the ambient environment, the novel transducer mechanism yields a high sensitivity and absolute accuracy optical sensor. Ready for direct use in many applications. Calibration service available upon request. The T620 sensor handling and installation is fast, easy and intuitive. Delivers the advantages inherent to FBG sensors.

The TFP10 is an all-fiber micro Fabry–Pérot (uFP) sensor for use in applications to 700°C. Using laser micro- machining technology, the Fabry–Pérot sensing element is hermetically embedded in the core of the host single-mode optical fiber. The advanced design yields an all-fiber, ultra- compact, very-sensitive, and high-accuracy sensor ideally suited for precise strain or pressure measurements to 700°C.

The TFP10 sensors have been applied to a large number of tests and measurements in the field and are reported to be uniquely positioned among the best fiberoptic high temperature sensors available today.

Our fiber Bragg grating based packaged sensors are available in a wide range of optical specifications and mechanical configurations. For custom OEM sensors, our company works closely with each customer to optimize the packaging for the sensors they would like to have manufactured by us. Technica undertakes a rigorous development process before products release. We are committed to continuous improvements after release to insure performance to the highest of standards.

World leader in fiber Bragg grating and micro Fabry–Pérot strain sensors. From ultra-small to large industrial strain sensor packaging, for strains from sub-microstain to 50,000 microstrain, for environments from cryogenic to 1000 °C, and with cores based on standard acrylate or polyimide coated fibers, or truly hermetic copper or gold coated fibers (T15, T25, T100, T130, T150, T170, T210, T220, T230, T240, and TFP10).

World leader in fiber Bragg grating and micro Fabry–Pérot temperature sensors.
