Bench-Top Optical Spectrum Analyzers by Yokogawa

These devices can be used to develop and enhance near-infrared and mid-infrared optical devices.

Yokogawa Test & Measurement Corporation has developed the AQ6375E and AQ6376E optical spectrum analyzers and will release them on July 29. These devices offer high-precision measurement of the optical spectrum in the near and mid-infrared bands, as well as greatly improved user-friendliness.

yokogawaThe AQ6375E and AQ6376E are bench-top optical spectrum analyzers that use dispersion spectroscopy, an industry first.

The design of the AQ6375E is optimized for measurements in the near-infrared range of 1.0-2.5µm (micrometers), while the design of the AQ6376E is optimized for measurements in the mid-infrared range of 1.5-3.4 µm. They can be used to resolve the wavelength components of optical devices such as semiconductor lasers and fiber lasers in order to assess their properties.

These devices can be used to develop and enhance near-infrared and mid-infrared optical devices such as those used in environmental measurement, where the measurement of carbon dioxide and methane concentrations is required, and in the health care and medical treatment fields, where blood glucose and blood cholesterol concentrations must be measured to calculate blood sugar levels.

Given the recent heightened concerns about the global environment, initiatives to reduce greenhouse and toxic gas emissions are gathering momentum. In the environmental measurement field, ever more resources are being invested in the development of laser absorption spectroscopy for use in sensors to measure greenhouse gas concentrations.

In the health care and medical treatment fields, advances are being made in the development of health monitoring sensors that use laser technology to perform non-invasive measurements of glucose and cholesterol levels in the blood, and optical coherence tomography (OCT) to perform cross-sectional imaging of bodily tissue structures.

The development of sensors to measure greenhouse gas concentrations and monitor health requires high-performance lasers that match the absorption wavelength of the measurement subject in the 2µm and 3µm bands, and so optical spectrum analyzers that can perform measurements of laser light with high wavelength resolution over a wide dynamic range are required. And for the development of OCT technology, optical spectrum analyzers that are capable of making batch measurements in the 1-2.4μm range are considered necessary.
