GL SPECTIS 1.0 Touch

GL SPECTIS 1.0 Touch is the World’s first smart spectrometer. A unique, reliable, precise and intuitively operated spectral instrument specifically designed for the measurement and characterisation of light sources – especially LEDs – providing accurate spectral information and colour co-ordinates conforming to CIE standards.

Dedicated software automatically calculates critical parameters such as colour temperature and colour rendering index, whilst different accessories are available for specialised measurements; including luminous flux using GL OPTI SPHERE 48, and luminance measurement of flat LCD and OLED panels, and plasma FPDs using GL OPTI PROBE 1.0 optical probe.

GL Optic has designed a product to face the challenges of the modern lighting industry and demanding LED market. This handheld spectrometer can be used for everyday incoming quality control of light sources, field work of quality engineers and other professionals who deal in the quality of light. GL SPECTIS 1.0 Touch is the measuring device of choice for the final assessment of lamps as well as for testing complete lighting installations.

Key Features:

  • Completely independant, portable device
  • High sensitivity and precise calibration
  • Colour LCD Touch screen
  • Various data transformation features: Wi-Fi, Bluetooth, USB cable, SD card slot
  • Android based operating system
  • Approximately 6 hours battery life

The following values are automatically calculated using built in software or PC-based GL SPECTROSOFT:

  • Tristimulus values XYZ
  • Chromaticity coordinates xy, uv, u’v’
  • Correlated colour temperature CCT (Kelvin)
  • Dominant wavelength (nm)
  • Colour rendering CRI (Ra)
  • Peak wavelength (nm)
  • FWHM spectral linewidth

GL SPECTROSOFT is a PC-based software, designed for laboratory application as well as for field work in production quality control and for general light assessment purposes. Key features include:

  • Intuitive and easy to use
  • Absolute or relative measurements
  • Flexible data presentation
  • Helpful tools for easy analysis and interpretation of measured spectra

The following measurements are performed with the use of additional optical probes:

  • Illuminance (lux)
  • Spectral irradiance (µW/m2/nm)
  • Luminous flux (lumens)
  • Spectral radiant flux (W/nm)
  • Luminous intensity (candelas)
  • Luminance, 2D & spot (candelas per sq. Meter)

Product Recommendations

“LED lighting is best tested with spectroscopic equipment; old-style lux meters and colour temperature devices are not so accurate for LED-based lighting. The GL Optic device allows us to rapidly and accurately assess the quality (brightness, colour, stability) of LED-based lighting installations. The GL SPECTIS 1.0 touch is a very fast spectrometer and easy to use in a field.”

Mike Simpson, Technical and Design Director, Philips Lighting

“It’s a great piece of kit and certainly gives our client and staff the confidence when surveying initial lighting opportunities.”

Martin Roche, Managing Director, The A+ Group
