New range of visible wavelength and optical spectrum analysers

11-09-2023 | Yokogawa | Test & Measurement

Yokogawa Test & Measurement Corporation has released the AQ6373E visible wavelength and AQ6374E wide-range optical spectrum analysers. Designed as successors to the AQ6373B and AQ6374, which feature high resolution and close-in dynamic range, the new analysers offer the same high level of performance as well as features that improve operability to meet a variety of optical spectrum measurement needs in both R&D and production settings.

Leveraging the technologies and expertise that it has acquired over the past 40-plus years in this field, Yokogawa has designed the AQ6373E and AQ6374E to meet the growing need to test new optical devices and components in the visible to near-infrared wavelength bands for medical, biological, and material processing applications. The new models improve usability while inheriting the high wavelength resolution and wide close-in dynamic range of the current AQ6373B and AQ6374 models, which have been highly evaluated as laser spectrum measuring instruments.

In the medical and biofields, light-emitting devices are increasingly used due to their accuracy and non-invasiveness, which demands precision measurement during development. For the manufacturing of semiconductors, the characterisation and quality testing of lasers used in the production process also require measurement by a high-performance optical spectrum analyser. Meanwhile, given the widespread use of tablets and smartphones, users have come to expect a touch-based and intuitive interface that allows even those unfamiliar with the diverse settings and functions of optical spectrum analysers to perform optical spectrum tests easily.

The AQ6373E optical spectrum covers the same wavelength range between 350nm and 1200nm as the current AQ6373B. As well as a standard performance model, the lineup includes a high-resolution model optimised for laser evaluation applications and a limited model designed for production testing applications.

The AQ6374E optical spectrum analyser can be used for evaluating light-emitting devices such as lasers and characterising optical fibres. It offers the high optical performance of the previous AQ6374 model, providing the industry's only wide measurement wavelength range (350-1750nm).

The new optical spectrum analysers feature improved usability, including an APP mode to speed up customers' R&D and production testing tasks. APP mode provides a DUT-specific user interface that guides the user from configuration setting to the output of test results so that even customers unfamiliar with optical spectrum analysers can operate them easily. They also have a large LCD touch panel, making operation easier and more intuitive.

The analysers meet the CE marking requirements.
