Instrument Systems KONICA MINOLTA Group CAS 140D Array spectrometer for high accuracy light measurement

High-end CCD detector, cooled and back-illuminated Down to 4 ms integration time Spectrograph with minimum stray light and enhanced throughput Integrated density filter wheel USB, PCIe or Ethernet interface “Plug & play” accessory identification The CAS 140D represents the fourth generation of the worldwide extremely successful series of high-end array spectrometers from Instrument Systems. The previous model CAS 140CT was for many years regarded as the standard for measurement accuracy in spectroradiometry. Now the CAS 140D is establishing a new benchmark. It combines all advantages of the...

02 \\ Equipment and mode of functioning Optimized optical and mechanical design The proven crossed Czerny-Turner spectrograph has been further optimized for even better stray light suppression and a wide dynamic range. The integrated density filter wheel manages without a mechanical position switch and ensures the exact positioning of the filter with an electronic Hall sensor. The CAS 140D thus extends the intensity measurement range to nine orders of magnitude. The instrument can easily measure both very low and very high light intensities. The filter wheel additionally assumes the...

The user merely mounts the desired measurement adapter ◄ Accessory identification ensures reliable use of different measurement adapters. The system automatically recognizes the connected accessories and ensures that only currently valid calibrations are used. on the spectrometer. The instrument recognizes which accessory has been mounted and automatically selects the correct calibration...

► Software solutions / LED, OLED & SSL measurement of a source meter or the storage and analysis of a sequence of fast measurements in burst mode. In addition, the SpecWin Pro and SpecWin Light support measurements according to the IES TM-30-15 method for the improvement of color perception. Besides the two metric values fidelity and gamut index, it also enables graphic evaluations such as Hue Bin tables and color-vector graphics. Software development kit with DLL and LabViEW driver A software development kit (SDK) is available for custom programming or integration into production...

Measurement adapters for CIE 127-oonformant evaluations All measurement adapters from Instrument Systems permit the CIE 127-conformant evaluation of radiometric and photometric quantities, as well as all relevant colorimetric parameters such as color coordinates, color temperature, color rendering index and dominant wavelength. Thanks to the fiber connector, they can be easily replaced without loss of calibration. Specially developed test sockets provide electrical power to the LEDs for precise launching of a light beam to the corresponding measurement adapter. Test sockets are available...

High-class determination of luminous flux and color with integrating spheres The CAS 140D also achieves impressive results in the measurement of photometric and colorimetric quantities such as correlated color temperature (CCT), color rendering index (CRI) and total luminous flux with the aid of integrating spheres. It is thus ideal for use by lamp manufacturers in production and quality control, where the required measurement accuracy is particularly high with regard to color coordinates. Due to the short measurement times of as little as 4 ms, the CAS 140D is also able to analyze the...

On the basis of the CAS 140D Instrument Systems also supplies system solutions for determining the classification of the energy efficiency of lamps and luminaires according to EU regulations. For this purpose the spectrometer is supplemented with the appropriate measurement adapters, integrating spheres and optical probes as well as goniometers, in order to measure the multitude of prescribed parameters. A special module of the SpecWin Pro software enables the evaluation of the energy efficiency measurements of the test sample and calculates key characteristics such as the energy efficiency...

The CAS 140D is coupled with a TOP 200 telescopic optical probe to form the DTS 140D complete system for spectral display measurement. It was developed for the highly precise analysis of radiance and luminance and the color of displays and backlit symbols. No matter which display technology is to be examined - be it an LCD, CRT, OLED or LED display - the display test systems of the DTS 140D series are universally applicable. In conjunction with a telescopic optical probe, the CAS 140D has a 50 % higher throughput than the previous model CAS 140CT, i.e. it can quickly measure extremely weak...

DTS 140D NVIS for testing night-vision compatible displays The DTS 140D NVIS was specially developed by Instrument Systems for testing displays and panels according to MIL-L-85762A and MIL-STD-3009. Based on robust array spectrometer technology, the system is an excellent choice for applications in production and quality assurance, where toughness and simple operation are required. Automated measurements are enabled by the pass/fail test functions of the SpecWin Pro software. One of the biggest challenges in taking NVIS measurements is correctly capturing the extreme differences in...
