Optical spectrum analyser for measurements on LEDs and laser light sources

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

High-speed measurements result from a standard sweep time down to one second (0.5 sec in automatic mode), while the free-space optical input makes the instrument applicable to 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. The large (10.4-inch) bright display features an intuitive graphical user interface, and operation can be controlled via USB mouse and keyboard as well as panel keys.

A large (128 Mbyte) internal memory is backed up by USB memory support, and a variety of built-in functions including filtering, automatic measurements and pass/fail testing provide easy data analysis. Fast remote operation is available via GP-IB, RS-232 and Ethernet.

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