GL Spectis 6.0 Features

Photometric and radiometric calibration

An absolute spectral calibration is integrated into each spectrometer before delivery thereby enabling the accurate measurement of different absolute values such as lux, candela or lumen together with radiometric values depending on the measurement accessory installed.

Dark Current Compensation

Despite the fact that it is not a cooled detector instrument, the Spects 6.0 is ready to provide very accurate measurements in different conditions. A temperature sensor installed on the electronic board monitors changes in temperature and automatically compensates for any change in dark current level ensuring excellent measurement stability.

Variety of integrating spheres and probes available

With the universal concept and design of the Spectis 6.0, you can easily expand your measurement system by adding any one of our integrating spheres or additional accessories.

Automatic accessory detection

The Spectis 6.0 possesses a unique mechanism to detect and automatically load the correct calibration file for that attached accessory. This enables the user to confidently avoid measuring errors when changing accessory interfaces. The calibration meets the requirements of leading standards institutes and is confirmed with a manufacturer’s certification.

Spectis 6.0 Metrics

Our preconfigured, individually calibrated LED spectroradiometers deliver fast and precise results for nearly any practical light measurement application. Measure in seconds and review the results directly on the handheld display or dig deeper with the optional analysis and automation software. Using the Spectis 6.0 rackmount spectroradiometer, you can measure any or all of the following optical quantities:

  • Lux – irradiance
  • Lumen – luminous flux
  • CRI – color rendering index according to the CIE
  • CCT – the color temperature according to standard CIE
  • Color – the chromatic coordinates of the CIE 1931 and CIE 1964
  • TM-30 – color rendering using the latest IES recommend approach
  • Fidelity and Gamut – method for evaluating light source color rendition according to TM-30 IES standard
  • PAR/PPFD – photosynthetic active radiation measurements for horticulture
  • EML – biological effects of light on humanism equivalent melanopic luxe

* Dynamic range is spectrum related and should be calculated separately for any light source. Estimated dynamic range for typical 4000 K white LED.
Range estimated for optical system made to default specification. Alterations of that are often possible. Please consult technical support if you are looking for specific parameters.

** Spectral range of the sensor. Actual spectral range of system may be reduced due to limitations of used optical accessory.

*** Absolute measurement uncertainty immediately after calibration. The expanded uncertainty corresponds to a coverage probability of 95 % and the coverage factor k = 2.
Parameters valid in laboratory conditions 25deg C, relative humidity 45%.

**** Applies only within the spectral range of the given model.
