The SpectralLED® Light Booth quickly simulates virtually infinite  lighting conditions enabling visual color assessment for  photography, product display or lighting design applications. Both  real and theoretical lighting conditions can be produced, enabling  CRI experimentation, analysis and optimization.

When coupled with our line of spectroradiometers and Light Touch software, a fully non-contact digital color measurement and imaging system can be configured.

Applications

  • Display visibility vs ambient lighting conditions
  • Textile and apparel analysis
  • Color consistency assessment
  • Verification of stain removal
  • Fade analysis

Unprecedented resolution and accuracy for CRI experimentation, analysis and optimization

  • All solid-state design for rapid start-up, repeatable performance and long operating lifetime
  • Built-in RMS spectral fitting for simulation of user imported spectra
  • Wavelength options from the UVA to the Near Infrared
  • Quickly simulate any CIE illuminant or Macbeth™ / X-RITE™ Color Patch
  • Constant current drivers & built-in optical feedback ensure accurate & flicker-free output in real-time
  • ISO/IEC 17025 accredited by NVLAP (NVLAP lab code 200823-0) for calibration accuracy

RS-7 WavemonTM   Multi-channel photodiode system with amplitude feedback and real-time wavelength measurement

The Wavelength Monitor System is a multi-channel photodiode system which provides amplitude feedback and real-time wavelength measurements. It consists of three photodiodes each with an independent transimpedance amplifier circuit. Proprietary optical filtering techniques allows for wavelength accuracy of +/-0.25nm and repeatability of +/-0.05nm. The Wavelength Monitor PCBA, photodiodes, and optical filter assembly is temperature stabilized using a Peltier cooler and thermistor in a PID feedback loop. This assembly is a discrete module which can be used with any RS-7 model.
