International Light Technologies has been developing and manufacturing high-performance light meters and measurement systems for over 50 years. Our comprehensive portfolio of light measurement products include radiometers, photometers, optometers, dataloggers, lux meters, chroma meters, spectrometers and spectroradiometers. These meters are designed to measure light in the IR, NIR, VIS and UV Range. Our meters are used for process validation, and research and development covering a broad range of applications including manufacturing, aerospace, medical, scientific, industrial, automotive, agriculture, healthcare, entertainment, military, marine, and more.
ILT offers NIST traceable, calibrated spectrometers and spectroradiometer system including integrating spheres, cosine correcting diffusers, fiber patch cords and our complimentary Spectrilight III software that easily and accurately measure spectral irradiance, photometry, color coordinates, CCT, illuminance, peak wavelength and more. UV spectrometers, broadband UV/VIS/NIR and IR spectrometers can be combined to cover a broader ranges. Our ILT950 and ILT550 spectrometers can be combined with many of our detectors and input optics for application specific light measurement solutions.

The ILT960-UVLS is a Low Stray Light version of the ILT960-UV. The ILT960UVLS-RAA4 includes ILT’s special zeroing filter to reduce stray light and noise and allow measurement of “no light”.
The ILT960-UV is ILT's new portable, compact UV spectrometer with increased broadband sensitivity. The ILT960 can measure UV light levels as small as .4 uW/cm2/nm. The ILT960-UV comes in three standard configurations. All systems come standard with SpectrILight III software, 1 meter long fiber, input optic, tripod, hard storage case, and NIST traceable, ISO1025 accredited calibration with certification and data files
The ILT960-VIS is a portable mini spectrometer used to measure both light amplitude and wavelength. The ILT960-VIS comes in four standard configurations. All systems come standard with SpectrILight III software, 1 meter long fiber, input optic, tripod, hard storage case, and NIST traceable, ISO1025 accredited calibration with certification and data files
The ILT960-BB is a portable mini spectrometer optimized for VIS-NIR light applications. The ILT960-BB comes in four standard configurations. All systems come standard with SpectrILight III software, 1 meter long fiber, input optic, tripod, hard storage case, and NIST traceable, ISO1025 accredited calibration with certification and data files
The ILT960-NIR is a compact, broad-band, portable, mini spectrometer optimized for NIR applications. The ILT960-NIR includes our RAA4 mini right angle diffuser, 1 meter long fiber optic light guide, rugged case, tripod, calibration and software.
The 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. Available to purchase in our eStore.
The ILT950-NIR is a cost-effective, fully-integrated spectroradiometer. The compact air-cooled NIR spectrometer uses a 256 pixel linear InGaAs array, and offers both a high-sensitivity and low-noise mode for measurements in the near infrared range, out to 1700 nm (1.7 micron).
For budget-conscious customers, the ILT560 Mini Spectrometer comes standard with a SMA905 receptor allowing it to be used a variety of fiber patch cords including both flexible and rigid models. The ILT560 systems are configured with all the accessories and calibration needed to measure Power, Irradiance or Radiance.
