Technica Optical Components Expands Optical Sensing Instruments Portfolio

On January 23, 2025, Technica Optical Components, along with its subsidiary Femto Sensing International, announced the launch of the W Series of optical sensing interrogators, a significant advancement in optical measurement technology. The star of this new series is the W4 optical sensing interrogator, which boasts a remarkable 160nm scanning range across four monitoring channels.

Unveiling the W4 Interrogator

The W4 instrument stands out for its economical commercial-grade design and its versatility in measuring both static and dynamic parameters. It operates efficiently in full spectrum mode at 10Hz, and when peak detection is necessary, it can function at an impressive 100Hz. This advanced device supports a staggering capacity of up to 44 Fiber Bragg Gratings (FBG)-based sensors on each channel, making it possible to monitor a total of 176 sensors simultaneously—an impressive feat for research and development teams in various sectors.

One of the significant features of the W4 interrogator is its state-of-the-art laser calibration technology that ensures higher accuracy and repeatability in measurements. The instrument boasts a repeatability of +/- 2pm, accuracy within +/- 10pm, and a dynamic range of 25dB, guaranteeing precise results across its defined scanning range. Its robust design includes no moving parts and eliminates the need for tunable filters, which enhances its reliability across varying temperatures, ranging from -15C to +55C.

Moreover, the interrogator is conveniently housed in a 1U rack-mountable enclosure, facilitating easy installation in laboratory or field settings. With these advanced specifications and reliable performance characteristics, the W4 is positioned as a prime solution for industries utilizing optical sensing technology in civil engineering, aerospace, energy, geotechnics, and medical applications.

Introducing the WS Interrogator

In addition to the W4, Technica also launched the WS optical sensing interrogator. This model features a 160nm scanning range but condenses its capabilities into a single monitoring channel. The WS is optimized for both static and dynamic measurements, supporting a full spectrum mode of operation up to 25Hz and a peak detection mode climbing as high as 1000Hz.

Significantly, the WS interrogator allows for expansion through compatible Fiber Bragg Gratings (FBG) and can seamlessly connect to the innovative 1xN Serial MEMS Optical Switch. This switch can accommodate varying capacities, including options for 16, 32, 64, 128, and 256 channels, thereby opening up numerous possibilities for organizations looking to enhance their measurement systems without the cumbersome hardware.

Applications and Implications

The W Series interrogators mark a transformative development in optical sensing technology, allowing for broader applications across numerous industries. Their ability to support high sensor capacity makes them particularly suitable for research and utility sectors, where comprehensive data collection is crucial. Feedback from previous series, including the FAZT, M, and S series, has been integrated into the new designs to meet the rigorous demands of clients in multiple fields like transportation, construction, security, and medical technology.

Both the W4 and WS models are designed not only for precision but also for scalability and ease of use, reflecting Technica's commitment to delivering top-tier optical solutions. As organizations increasingly rely on data-driven decisions supported by sophisticated measurement tools, the W Series will undoubtedly play a pivotal role in the optical sensing market.
