Yokogawa introduces optical spectrum analyser

Suitable for areas such as resolution, accuracy, sensitivity, measurement speed and dynamic range, the AQ6373 features a colour analysis function that makes it ideal for measurements on light-emitting diodes (LEDs) and laser light sources.

Key performance parameters include a wavelength accuracy of +/-0.05nm, a wavelength resolution down to 0.01nm and a sensitivity of -80dBm, switchable to a choice of high-dynamic-range modes.

High-speed measurements result from a standard sweep time down to one second (0.5 seconds in automatic mode), while the free-space optical input makes the instrument applicable for use with single-mode, multimode and large-diameter-core fibres.

A built-in light source is also provided to aid optical alignment.

The AQ6373 offers excellent functionality and operability, with ease of operation and data handling, according to the company.

The 10.4in (26.4cm) bright display features a graphical user interface and operation can be controlled via USB mouse and keyboard as well as panel keys.

A 128Mbyte internal memory is backed up by USB memory support, while a variety of built-in functions including filtering, automatic measurements and pass/fail testing facilitate data analysis.

Fast remote operation is available via GP-IB, RS-232 and Ethernet.

Key application sectors for the AQ6373 are in the research-and-development evaluation and production testing of high-performance short-wavelength lasers, filters and LEDs - devices that are used in a variety of sectors, including medical analysis and treatment, biological microscopy, industrial machining, telecommunications, optical rangefinding and interferometry and consumer electronics.
