International Light ILT350 Spectrophotometer

Hand-held Illuminance Spectrophotometer

The hand-held ILT350 Illuminance Spectrophotometer was 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 colour 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 not only lux & foot candles, but also spectrum, CRI, CCT, tri-stimulus values, and more.

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

The ILT350 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.

Applications include: 

  • Automotive Lighting
  • Commercial and residential lighting designs and upgrades
  • Display booth, colour and spectrum
  • Comparison of traditional sources to LEDs
