SPM068 Spectrum Response CurveWith the ILT5000, it's all about supplying fast, reliable data to your computer for analysis. Our extensive DataLight III light measurement software is available for Windows 7, 8 & 10 and MAC OS X.

The Meters App allows transmission of measurement data via USB or wirelessly. Additional features include single/multi-system graphical display, single reading capture and data recording, auto ranging, zero, hold and integrate.

SPM DetectorSPM068/QNDS3/W Photomultiplier detector with built-in power supply is equipped with a quartz cosine correcting diffuser for taking accurate irradiance measurements in very low light level applications such as transmission, bioluminescence, phosphorescence, safety marking, and photon counting. The detector comes equipped with a QNDS3 attenuator to prevent overexposure of the detector but it may be removed for ultra-sensitive light measurements. The detector has two gain modes - high and low - to vary the dynamic range to suit the measurement application. Calibrations in W/cm2 with and without the QNDS3 are provided.

Dynamic Range: With QNDS3: 1e-9 to 1e-2 W/cm2 (low gain mode) or 1e-11 to 1e-4 W/cm2 (high gain mode) or

Without QNDS3: 1e-13 to e-5 W/cm2 (low gain mode) or 1e-14 to 1e-7 W/cm2 (high gain mode)

(Note: Ranges are based on conservative averages. Take care not to approach noted on the sensor calibration certificate to prevent irreparable damage to the PMT from saturation.)

Measurement Range: 230-700 nm
Dimensions: 112 mm x 42 mm dia.
Ordering part#(s): ILT5000, SPM068/QNDS3/W. (Include calibration in Low gain mode with and without QNDS3. Additional PIR calibrations can be added for High gain mode as needed.)

Filters and input optics are removable and may be ordered separately from the detector assembly to allow filter and input optic swapping.

DataLight III Software:

With the ILT5000 its all about supplying fast, reliable data to your computer for analysis. Our extensive DataLight III light measurement software is available for Windows PC, Tablet and MAC computers. DataLight III includes our set it and forget it remote internal data storage app., and an improved All-in-One meters app for control and transmission of data using a mini USB cable or wireless data transmission.

DataLight III Software API

For simultaneous multi-sensor data logging, ILT also offers the ILT6000 Rack-Mount Radiometer System with the same specifications as the ILT5000 in a 2-10 unit, rack mountable housing.
