Instrument Systems shows spectroradiometers at Photonics West
Systems offer fast high-resolution characterisation of lasers and VCSELs
As a participant at the German pavilion at Photonics West / USA, Instrument Systems is showing its premium class spectroradiometers. The globally recognised reference device CAS 140D forms the basis of the system and is supplemented by a 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 colour coordinates, colour temperature or colour 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.
High-resolution spectroradiometry
Instrument Systems developed the CAS 140CT-HR high-resolution array spectroradiometer specifically for the absolute characterisation of narrow-band emission sources. It delivers measurement results with a high spectral resolution of up to 0.2 nm half-band width, accompanied by short measurement times as low as 9 ms. Above all, the CAS 140CT-HR offers decisive advantages compared to conventional technologies for the fast testing of laser diodes or VCSEL.
Dispersive, scanning or Fourier-transformed IR spectrometers (FTIR) have movable parts that react sensitively to production vibrations. The CAS 140CT-HR contains fixed components and is 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 fibre. Due to the flexible fibre connector, the measurement adapter can be easily 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 universally employed for display technology, e.g. LCD, LED or OLED.
