Flat Response Curve

Rugged, Compact, Multi-purpose, Multi-point Smart Sensor for VIS-NIR Radiometric Measurements

Designed for a wide variety of visible and near-IR irradiance measurements, including transmission and reflectance measurements. ILT1000/F/W  flat response irradiance monitor measures 400-1064 nm with an average measurement range of 8e-8 to 7e-2 W/cm2. (ILT1000, F filter, W diffuser and PIR calibration)

Measurement Range: 8e-8 to 7e-2 Watts/cm2
Spectral Range: 400 - 1064 nm
Order part numbers: ILT1000, F filter, W diffuser and PIR calibration

ILT1000 can be used remotely when powered by any USB source (wall, phone charger, computer, portable power bank) and record readings using the “Set it & forget it” datalogging software.

For wired monitoring we offer three easy to use software packages. CLI for the technical savvy customers who wish to write their own code. Trend and Bar.



TREND - Records all 6 parameters while displaying the trend over time for the user switchable parameter. Multiple examples of trend can be run simultaneously to allow multi-unit comparisons.

BAR - Allows multi-system, datalogging and displays the user switchable parameter in a bar graph. The expandable graph can accommodate up to 32 systems simultaneously with use of hub(s). User can enter nicknames for each unit to define the location, application, version, serial number, etc. Customer can program max and min warning levels and use color coded bar responses for easy troubleshooting.
