Spectrometers / Spectroradiometers

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. 

Calibrated Spectrometers

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 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.
