Your Trusted Partner in UV Light Testing
The ILT970-UV Spectroradiometric Measurement Systems are ideal for testing and measurement of UV light sources. We offer three options for
measuring spectral irradiance from 200 nm to 450 nm and two options for spectral flux from 250 nm to 450 nm. Each Spectroradiometer includes
the UV 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 and storage case.
These Spectroradiometers 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. Ideal for product development, inspection, and production, ILT’s Spectroradiometric Measurement Systems offer the precision and reliability your project demands.

- ILT970UV-RAA4 - Right angle adapter/diffuser head with 11 mm aperture and mini-integrating sphere for measuring spectral irradiance, total irradiance, and spectral characteristics of light sources
- ILT970UV-W/A2 - Silica chip head with SMA adaptor for measuring spectral and total irradiance, illuminance, color parameters, and spectral characteristics of light sources.
- ILT970UV-W5E - Miniature cosine correcting diffuser with SMA905 fiber adaptor for measuring spectral and total irradiance, color parameters, and spectral characteristics of light sources
- ILT970UV-INT50 - 5 cm (2”) integrating sphere for measuring forward and total spectral flux, power in watts, and spectral characteristics.
- ILT970UV-INT150 - 15 cm (6”) integrating sphere for measuring forward and total spectral flux, power in watts, and spectral characteristics.
Versatile
The ILT970-UV 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.
