Fast, high-resolution characterization of laser and VCSEL light sources

At Photonics West / USA Instrument Systems presents high-resolution spectroradiometers for the characterization of laser light sources and displays.

As a participant at the German pavilion, Instrument Systems is showcasing its premium class spectroradiometers at Photonics West / USA. The globally recognized reference device CAS 140D forms the basis of the system and is supplemented by our special model, the high-resolution CAS 140CT-HR. Both devices can be viewed in simulated applications at exhibition booth 4545-38 from 5–7 February 2019. In combination with various accessories, the color coordinates, color temperature or color rendering index of LED modules and displays can be measured with the highest level of precision. As they are particularly stable and reliable in operation, the array spectroradiometers of the CAS series are ideally suited to 24/7 use in the production line. The design of the CAS 140CT-HR is specially aligned to the measurement of narrow-band emission sources such as laser diodes or VCSEL. The extremely high spectral resolution of up to 0.2 nm full width at half maximum and particularly short integration times as low as 9 ms permit fast testing in the laboratory and production.
