Light Meters

Light Meters

Full line of precision, configurable digital Light Meters (ILT10, ILT10C), Light Meter/Monitor/Data Logger (ILT1000), Radiometers (ILT6000, ILT5000, ILT1700, ILT1400, ILT70 Series) and Belt Radiometers (ILT400, ILT490) - visible, UV and infrared light.


Spectroradiometer Family


Portable, NIST Traceable, calibrated spectroradiometers that easily and accurately measure spectral irradiance, color coordinates, and CCT from the UV to the near-infrared.



Light Measurement Detectors

Light Measurement Detectors

Light measurement detectors are used with light meters to collect a specific type of light that the meter is calibrated to accept.

Optical Filters for Light Measurement Detectors

Light Measurement Optical Filters

Optical filters are often used with light measurement detectors and meters to attenuate certain wavelengths of light and produce an overall desired detector response.

Accessories for Light Measurement

Light Measurement Accessories

International Light Technologies offers a wide variety of light measurement accessories including tripods, power cords, computer and extension cables, cases and underwater sensor modifications.

Input Optics for Light Measurement

Light Measurement Input Optics

Input optics change the optical geometry of a light measurement in order to collect information about a light source that cannot be acquired by a detector alone.
