Research Light Meters

ILT research light meters are user-configurable for use as both radiometers and photometers. A vast array of interchangeable radiometric and photometric sensors, input optics and accessories allows for measurements of irradiance (W/m²), illuminance (lux), luminous or radiant intensity (candela or W/sr) as well as the total integrated dose/exposure in joules, J/cm², lux*seconds and more. Sensors are available off-the-shelf covering the entire UV to NIR range. All systems are NIST calibrated including ISO/IEC 17025:2017 accreditation. Compared with our pre-configured radiometers, sensor heads and accessories on research instruments can be swapped, allowing a user to adapt their meter for a variety of applications.
