International Light ILT5000 Research Radiometer

Research Radiometer and Picoammeter

The ILT5000 is the ILT1700 for the 21st Century.  Improvements on the industry standard ILT1700 include rapid optical measurements (1-100 Hz), a broader dynamic range (100 fA to 1 mA), Datalight III for PC and Mac, plus built-in wireless, data storage, and rechargeable batteries.

The ILT5000 is backwards compatible with the ILT1700 sensor configurations, as well as all of ILT’s sensor accessories including filters, optics, integrating spheres and ISO 17025/NIST traceable calibrations.

ILT5000 optical measurement systems typically consist of the ILT5000 light meter, a sensor, filter, optic and calibration to allow direct reading in the appropriate empirical units including lux, foot-candles, candela, lumens, watts, W/cm2, cd/m2, foot-lamberts, nits, etc.

The ILT5000 meter requires a sensor to measure light. Sensors are available to measure from 185 nm out to 40 micron and are supported with a vast array of accessory including bandpass filter, cosine receptors, integrating sphere, and numerous types of calibration.
