Instrument Systems showcasing fast, high-resolution spectroradiometers for laser and VCSEL characterization

In the German pavilion at Photonics West 2019 in San Francisco (5-7 February), Instrument Systems GmbH of Munich, Germany (a subsidiary of Konica MinoIta Group since 2012) is showcasing its premium-class high-resolution spectroradiometers for the characterization of laser light sources and displays. The reference device CAS 140D forms the basis of the system and is supplemented by the high-resolution CAS 140CT-HR model. Both devices can be viewed in simulated applications in booth 4545-38.

In combination with various accessories, the color coordinates, color temperature or color rendering index of LED modules and displays can be measured with highest precision. As they are said to be particularly stable and reliable in operation, the CAS series of array spectroradiometers is suited to 24/7 use in the production line.

High-resolution spectroradiometry

Instrument Systems developed the CAS 140CT-HR high-resolution array spectroradiometer specifically for the absolute characterization of narrow-band emission sources. It delivers measurement results with a high spectral resolution of up to 0.2nm half-band width, accompanied by short measurement times as low as 9ms. In particular, the CAS 140CT-HR is said to offer advantages compared with conventional technologies for the fast testing of laser diodes or vertical-cavity surface-emitting lasers (VCSELs). Dispersive, scanning or Fourier-transformed infrared spectrometers (FTIR) have movable parts that react sensitively to production vibrations. The CAS 140CT-HR contains fixed components and is said to be particularly stable and reliable in operation, making it suitable for exacting tasks in production and the laboratory.

Display measurements set up individually

Premium spectroradiometers can be set up as a DTS system for individual display measurements. The light radiation is launched with the TOP 200 telescopic optical probe connected to the spectrometer by an optical fiber. Due to the flexible fiber connector, the measurement adapter can easily be changed and the system quickly configured for other applications, e.g. LED measurement. The system measures, among other things, the radiance and luminance and the color of displays and backlit symbol displays. The DTS system can be employed universally for various display technologies (e.g. LCD, LED or OLED).
