ILT spectroradiometers are used for measuring spectral irradiance, spectral radiance and spectral radiant flux between 200-1700nm. Compared to a filtered radiometer or photometer, a spectroradiometer performs measurements spectrally and the radiometric, photometric and colorimetric properties are computed.
The ILT range comprises five models. The ILT 350 is a convenient, handheld spectroradiometer, much like a “lux meter”, but reporting illuminance as well as chromaticity, colour temperature and colour rendering. The ILT570-VIS is a miniature spectroradiometer for visible light sources from 400 – 800 nm.
The ILT 970 is a family of versatile, research-grade spectroradiometers, also available with a range of application-specific input optics.
The ILT970-UV Spectroradiometric Measurement Systems are ideal for testing and measurement of UV light sources. The ILT970-UV family includes three systems for measuring spectral irradiance from 200 nm to 450 nm, and two options for measuring spectral flux from 250 nm to 450 nm. The ILT970-BB series offers broad-band spectroradiometer for measuring light sources from 200 – 1000 nm, optimized for the ultraviolet (UV), visible (VIS), and near-infrared (NIR) spectral regions. Choose from five options for measuring spectral irradiance and spectral flux. The ILT970-VNIR family is optimized for the visible (VIS) and near infrared (NIR) spectral region from 380 – 1000 nm.
The ILT970-NIR family of Spectroradiometric Measurement Systems is optimized for the near-infrared (NIR) spectral region calibrated from 970 nm to 1650 nm.
The ILT970 and ILT570 spectroradiometer systems are fully characterized and are calibrated for their spectroradiometric response following ISO 17025:2017certified processes, and supported by global recalibration centers in North America, Europe, and China.
