Optical Spectrum Analyzer

An Optical Spectrum Analyzer (or OSA) is a precision instrument designed to measure and display the distribution of power of an optical source over a specified wavelength span. An OSA trace displays power in the vertical scale and the wavelength in the horizontal scale.

The expanding field of optics related applications has created a vast variety of industries and organizations that require advanced optical spectral measurements for both R&D and manufacturing. These industries include telecommunications, consumer electronics, healthcare, life science/medical research, security, sensing, microscopy, and gas/chemical analysis, and environmental monitoring.

Yokogawa (formerly Ando) is the global leader in optical spectrum analyzers, delivering high quality, cutting edge technology with dependability, performance and flexibility for over thirty years.

3400 NM OPTICAL SPECTRUM ANALYZER AQ6376

The AQ6376 is the latest version of our bench-top optical spectrum analyzer extending the wavelength coverage well beyond the NIR range of our previous models into the MWIR region from 1500 to 3400 nm.

Popular applications include the detection of gases such as carbon oxides (COx), nitrogen oxides (NOx), and hydrocarbon gas (CxHy) for environmental studies.

Similar to the long wavelength model, it offers the added benefits of gas purging input ports / output ports, a built-in cut filter for high order diffracted light, and a novel double speed mode which increases the sweep speed up to 2 times compared to the standard sweep mode.
