New optical spectrum analysers covering a wide wavelength range

Yokogawa has launched two new optical spectrum analysers (OSAs) to fulfil market demands for an instrument capable of measuring a wide range of wavelengths to meet new optical product development and manufacturing needs.

The Yokogawa AQ6375E and AQ6376E are the only grating-based OSAs covering SWIR over 2μm and MWIR over 3μm with world-class optical performance.

Building on the pedigree of Yokogawa’s AQ6375B and AQ6376 OSAs, the new OSAs are offered in four versions.

The AQ6375E Standard has a wavelength range of 1200-2400nm; the AQ6375E Extended Wavelength version has a wavelength range of 1000-2500nm; the AQ6375E Limited version has a wavelength range of 1200-2400nm (with reduced wavelength resolution); and the AQ6376E Standard has a wavelength range of 1500-3400nm.

The choice of available wavelengths gives developers increased flexibility to apply the OSAs in various applications.

These include environmental measurement and gas sensing, where the AQ637xE can be used to measure gas absorption spectra and the characterisation of light sources used in Laser Absorption Spectroscopy.

Other major uses for the new OSAs are medical care and biotechnology, and industrial laser applications.

Typical applications will include the development and measurement of lasers; the characterisation of broadband light sources such as supercontinuum light sources; optical passive devices; and optical fibres.

“The new AQ637xE has been launched to give developers and manufacturers greater flexibility in the range of wavelengths they can measure, all in one highly accurate and very useable family of OSAs,” says Terry Marrinan, Yokogawa Test and Measurement’s Vice President and Chief Marketing Officer.

“The AQ637xE will extend the number of optical products that can be analysed, both in development applications and in production, bringing feature-rich, high accuracy measurement to all stages of the process.”
