ILIT960-VIS Spectroradiometer

Part Number: ILT960-VIS US
Request More Information

The ILT960-VIS is a compact portable mini spectrometer used to measure both the lights amplitude and wavelength and provide calibrated spectral irradiance, radiance or power measurements. The ILT960 kits are combined with high end optics for proper light collection including diffusers for cosine correction, integrating spheres for total flux and radiance barrels for a narrow FOV.  All ILT960 spectrometers include both wavelength and optical NIST traceable - ISO/IEC 17025:2017 Accredited calibrations with certification and data files. Complimentary SpectrILight III software is included at no cost and DLL’s are available upon request.

The ILT960- VIS Systems Have Been Optimized For VIS Light Applications And Comes In 4 Standard Configurations:


Options:

ILT960 with accessories

All systems come standard with SpectrILight III software, 1 meter long fiber, input optic, tripod, hard storage case, and calibration
 

Four standard configurations:
 

  • ILT960VIS-RAA4 (Right angle optic with 11 mm aperture, irradiance/illuminance cal.).  Available for purchase in our eStore!
  • ILT960VIS-INS50 (includes 2” integrating sphere with 7 mm port, 1m fiber, flux/power cal.)
  • ILT960VIS-R2 (Radiance barrel with 2 deg FOV, radiance/luminance cal.)
  • ILT960VIS-W (Diffuser 1” surface area, 1m fiber, irradiance/luminance cal.)

 


Versatile

One ILT960-VIS can be used with numerous input optics. Each input optic requires its own unique calibrations, however multiple calibrations can be performed on a single spectrometer, allowing measurements of total flux (W, lm), irradiance (W/cm2), radiance (W/sr/cm2), luminance (cd/m2), and illuminance (lux) with just one system

SpectrILight III Software


SpectrILight™ III is a LabView™ based software package for Windows that allows you to acquire spectral and color data.  Analysis of the data is now calculated instantly within the same program - no exporting required!
 
SpectrILight™ III includes calculations for metamerism, and 2 and 10 degree observer. The overlay feature allows the user to compare the base reading to current readings.  Wavelength range, integration time, scan average and other controls can be easily set through pop up windows, menus and tool bars.  Absolute irradiance and chromaticity are calculated instantly.
