Buying Optical Strain Sensors

Fiber technology to sense the world.

See us at SPIE Photonics West 2025 in San Francisco, January 25–30 (booth 1358)!

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-microstrain 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).

Bringing light to measurement

The FS62 optical strain sensors of the newLight sensor series are designed to easily retrieve static and dynamic strain measurements for stress analysis in smart materials, machines, components, and other types of structures.

With different encapsulations, materials, and attachment methods, they fulfill the requirements of strain measurements for smart materials testing, laboratory, and structural health monitoring (SHM) applications. Fiber Bragg Grating (FBG) strain sensors from HBK are available in two configurations: Linear configuration for measuring strain in a single direction. This is the ideal configuration for monitoring or stress analysis on a well-known direction. Rosette configuration, comprising three Fiber Bragg Gratings (FBG) on the same fiber and substrate. Measurements are taken in different directions for biaxial stress analysis with a single installation and small footprint.

FBG based strain sensors are devices that are commonly used by engineers to measure the effect of external forces on an object. They measure strain directly, which can be used to indirectly determine stress, torque, pressure, deflection, and many other measurements.
