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 light meters can be customized for system integration and OEM resale. If you are interested in customization or OEM options, please contact our sales department at 978-818-6180 x 116, or by filling out the contact form at the bottom of this page..

ILT light meters are easy-to-use, high performance instruments perfect for use as photometers (lux & chroma meters), intensity meters (candela), UV test (dose and exposure meters), power meters (watts or lumens), and flash light meters (high-intensity pulsed light, Xenon or LED strobe lamps). Most of ILT's Light Meters, Radiometers and Photometers can be configured with almost any one of our large selection of application-specific light sensors (light detectors), input optics, and light measurement accessories. Our ILT800 belt radiometer is self-contained and has specific spectral response models available.

The ILT2400 is a portable easy to use light meter loaded with features and applications all accessible on a large full color touch screen display. Simple touch screen operation allows users to view numerical and graphical output of light measurements in lux, fc, W/cm2, W, candela as well and the total integrated dose/exposure in joules, J/cm2, Lux*seconds and more. Sensors are available off the shelf covering the UV range to the IR range. All systems are calibrated in our NIST calibration lab and include ISO17025 accredition.
The ILT800 CureRight is a feature-rich profiling UV test system that delivers unmatched flexibility and capability not found in any other system. The ILT800 works on traditional light sources such as flood and Spot cure, UV LED sources, and pulsed light source. The large OLED display provide both a numerical value and a profile (graph) with both irradiance and dose/exposure.
The ILT800-UVF Hand-Held UV LED Light Meter has been designed specifically to measure UV LED sources including individual chips, LED arrays, spot lights, curing lamps, conveyor/belt systems, chambers, fiber optic light guides, curing wands, and more. Measures UVA and VIS from 360 - 450 nm. Available to buy in our eStore.
The ILT2500 CW and Pulsed/Flash portable light measurement system combines all the excellent features of the ILT2400 light meter, the broader measurement range of a research radiometer, pulsed light profiling similar to an oscilloscope, and the spectral measurement capability of a spectrometer.
The ILT5000 is the replacement for the ILT1700 light meter! Its smaller size makes it at home in the lab and in the field. Advancements include rapid optical measurements for graphically profiling the output of intense pulse light sources, a broader measurement range, Datalight III for PC and Mac, an iPhone app, plus built-in wireless, data storage, and rechargeable batteries!
The ILT1000 is a self contained light meter and sensor in a low profile housing. The versatile UV, VIS and IR datalogging optometer is capable of measuring 8 decades of light intensity (ie nW/cm2w- W/cm2) and providing direct readout in many calibrated units of readout including W, W/cm², J/cm2, Lux, lux*s, Fc, Lumens, cd/m², cd, W/sr, W/sr/cm² and more. The 4-20 mA output can be connected to a PLC for process control. An extensive API is provide for custom programming.
The ILT10C Light Meter is ILT’s most economical light measurement system. The ILT10C reads out in either Lux or Foot Candles in the human eye Visible range (400-700 nm) and is designed for use in a wide variety of applications needing a quick, accurate light measurement. Available to purchase in our eStore.
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 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 is equally at home on the production floor as it is the laboratory, combining high performance, accuracy, ease-of-use, and a wide array of features all in a rugged, compact, portable design. The excellent performance of the ILT950 has been improved even further with the addition of a new CMOS detector allowing for faster response and data transfer rates as well as a more balanced overall spectral sensitivity, and integration times as brief as 30 µseconds. The ILT950 is available in both UV and broadband UV/NIR models.
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.
