ILT350 ScreenshotThe hand-held ILT350 Chroma Meter is an illuminance spectrophotometer designed for portability, quality and ease of use. The housing design is ergonomic and light weight yet packed with features such as a built in full color display. Extensive data capture and analysis software, rechargeable battery and internal data storage. The menu buttons are intuitive and easy to use.


The built-in 12 mm diameter cosine receptor is protected by a magnetic rubber cap that remains attached to prevent loss or damage. The toggle buttons allows the user to easily scroll up and down to view readouts between lux & foot candles, spectrum, CRI, CCT, W/m2 PPRF, umol/m2 *s and more.


The ILT350 light spectrum meter has three measurement speeds including Fast (0.5 s), Slow (2.5 s) and Auto (0.5 – 27 s) depending on light intensities (20 lux to 100K lux). The spectral resolution is approximately 10 nm with an accuracy of ±3 nm. Relative spectral distribution data is exported in 1 nm increments using the light meter software.


The internal memory can store up to 100 files and export data into Excel/Work formats.


Applications include: 

  • Monitoring Bilirubin light source used for phototherapy treatments of Jaundice (hyperbilirumenia)
  • Measure irradiance and spectrum of white light (visible light sources)
  • Automotive Lighting
  • Commercial and residential lighting designs and upgrades
  • Display booth, color and spectrum
  • Comparison of traditional sources to LEDs
  • Light efficiency testing
  • Light safety and conformance to standards for:
    • Task lighting
    • Parking lots
    • Signage 
    • Light pollution analysis and more


The ILT350 is the recommended replacement to Ocean Insight's WaveGo miniature spectrometer
