Optical spectrum analyser

The AQ6376 optical spectrum analyser from Yokogawa is aimed at environmental monitoring, medical and biomedical industry specialists.

Yokogawa has launched its AQ6376 Optical Spectrum Analyser (OSA). This device sets a new ‘world standard’ for grating-based OSA capabilities in measuring signals with a wavelength beyond 3 µm,  designed to operate in the short-wavelength infrared (SWIR) as well as in the mid-wavelength infrared (MWIR) regions.

Terry Marrinan, VP of Sales and Marketing at Yokogawa Europe BV, said; “The AQ6376 has been developed to answer customer needs for a compact, high-performance OSA that is also easy to use and maintain. We’ve worked with a number of academic researchers and optical device manufacturers in its development to focus our efforts on the features and capabilities they need most. We believe this new product reinforces Yokogawa’s leadership in the high-performance OSA market.”

The new analyser covers wavelengths from 1500 to 3400 nm. It uses an advanced monochromator design that helps to separate spectral signals in close proximity to one another, and improves the dynamic range by reducing the influence of stray light.

The AQ6376 is aimed specifically at the needs of academic researchers and optical device manufacturers with their own in-company laboratories, active in environmental monitoring and bio/medical industries. It marks a breakthrough in performance, ease of use and price, minimising the size and setup time of the system, and being much less expensive than most alternative tailor-made systems it therefore delivers the best price/performance ratio of any OSA on the market.

Launched globally to coincide with the SPIE Photonics West show in San Francisco, the AQ6376 is available immediately in Europe. Its market leading capability to handle wavelengths of up to 3.4 µm is matched by high measurement speeds of up to 0.5 sec/100 nm, simple set-up (the self-calibration procedure takes less-than 2 minutes) and easy operational features (for example, a data-logging function for recording analysis results such as multi-peak measurements at up to 10,000 points per channel with time stamps which can be displayed in table and graphical formats, storage of the optical spectrum of each measurement for reviewing and troubleshooting, and a Windows file sharing function in addition to Ethernet/GPIB and USB interfaces for transfer of data.)

The AQ6376 is designed for measurement in many different application areas of photonic technology such as environmental monitoring for air pollution analysis, Infra-Red (IR) spectroscopy, scientific and medical diagnostics, and the nonlinear super continuum light generation. It will therefore enable manufacturers of light sources or passive optical components to save development time and further improve the measurement precision of their devices.

Terry Marrinan concluded; “The AQ6376 offers medical, biomedical and environmental management experts extended analysis capabilities. This device answers the research community’s demand for a compact, all-in-one, grating-based OSA that delivers state-of-the-art performance. We hope it will therefore contribute to more cost-efficient innovation and help deliver new developments in these important research areas.”

The AQ6376 has been developed for research applications such as fluorescence spectroscopy, absorption spectroscopy, NIR spectroscopy, IR spectroscopy, MALDI (Matrix-Assisted Laser Desorption/Ionisation), Confocal laser scanning microscopy, Laser Induced Fluorescence (LIF) and Laser surgery.
