ILT970-VNIR Spectroradiometric Measurement Systems
The ILT970-VNIR Spectroradiometric Measurement Systems optimized for the visible (VIS) and near-infrared (NIR) spectral regions calibrated from 380 nm to 1000 nm. Choose from seven (7) options for measuring spectral irradiance (W/ cm2-nm), spectral radiance (W/cm2-sr-nm), and spectral flux (W/nm). Each Spectroradiometer includes the VNIR spectrometer and optical fiber, an optical measurement head for spectral irradiance or spectral flux, a stand, SpectriLight III control software and DLLs, and a carry/storage case.
These Spectroradiometer Systems have been fully characterized and are calibrated for their spectroradiometric response following ISO 17025-certified processes, and supported by global recalibration centers in North America, Europe, and China.
VIS NIR Spectroradiometers for measuring:
• Spectral Irradiance, Irradiance, Illuminance and Color
• Spectral Radiance, Radiance, Luminance and Color
• Spectral Flux, Optical Power, Lumens and Color
Ideal for:
• Color Management
• Light Source Characterization
• Inspection, Validation, Production Test and R&D

- ILT970VNIR-R2 - Optical Head with an average field of view of 2 degrees for measuring spectral and total radiance, luminance, color parameters, and spectral characteristics of extended light sources
- ILT970VNIR-R3 - Small Spot, 500 mm fixed distance Optical Head for measuring spectral and total radiance, luminance, color parameters, and spectral characteristics of extended light sources
- ILT970VNIR-INT50 - 5 cm (2”) integrating sphere for measuring forward and total spectral flux, power in watts, and spectral characteristics.
- ILT970VNIR-INT150 - 15 cm (6”) integrating sphere for measuring forward and total spectral flux, power in watts, and spectral characteristics.
Versatile
The ILT970-VNIR can be paired with additional 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.
