The Labsphere Illumia Pro 2 UV integrating sphere spectroradiometer system is purpose designed for measuring the optical, thermal and electrical performance of UV LEDs and LED modules over a temperature range of 20-85°C and over the complete UV spectral band of 200-400nm. This includes the UVC band (200-280nm) that’s important for germicidal disinfection.
The intensity, spectrum and life expectancy of an LED or LED-based luminaire vary greatly both with drive current and junction temperature. By measuring the performance characteristics of the LED over a range of drive levels and temperatures, one can model the expected light output and life expectancy.
Labsphere Illumia Pro 2 UV Overview
The Labsphere Illumia Pro 2 UV integrating sphere spectroradiometer system is purpose designed for measuring the optical, thermal and electrical performance of UV LEDs and LED modules over a temperature range of 20-85°C and over the complete UV spectral band of 200-400nm.

By measuring the performance characteristics of the LED over a range of drive levels and temperatures, one can model the expected light output and life expectancy.
Illumia Pro 2 provides for automated thermal, optical and electrical characterization of UV LEDs, LED modules and solid state lighting (SSL). Integral® software allows users to measure the optical and thermal characteristics of various LEDs and arrays quickly, accurately, and simultaneously. The system includes a thermoelectric cooling stage for temperature control and monitoring. With a Keithley® SourceMeter®, the Illumia Pro 2 enables full current, voltage, and temperature sweeping – reporting radiant flux at your required intervals.
Advanced Sphere Design
The measurement of total radiant flux is performed in a 150mm (6 inch), UV-resistant, Spectralon integrating sphere in a 2π geometry. It goes without saying that all Illumia sphere systems incorporate auxiliary correction to compensate for the self-absorption of the device under (DUT) test placed within the sphere or at the sphere port. Without this essential option, measurements of luminous flux and chromaticity would suffer from errors easily running into the many tens of percent.
The Illumia Pro 2 UV sphere system comprises the following main modules:
High Performance UV-Optimised Spectrometer
The Illumia Pro 2 UV system is configured with the high performance CDS-2600-UV spectrometer that provides for measurements over the range 200-400nm. The CDS-2600 is based upon a back-thinned and TE-cooled CCD sensor which results in high sensitivity and low noise. Performance is further optimised with stray light correction. For more details on the spectrometer, click on the “Spectrometer” tab above.
Integral® System Software
Labsphere’s Integral® software drives the Illumia Pro 2 UV system, allowing you to operate your spectroradiometer from any device at any location and in multiple languages. Integral software also communicates with third party power supplies (AC & DC) as well as power meters, temperature monitors and temperature controllers.

High Speed UV-Optimised Spectrometer
The Illumia Pro 2 UV system is configured with the high performance CDS-2600-UV spectrometer that provides for measurements over the range 200-960nm (radiometrically calibrated range is 200-400nm). The CDS-2600 is based upon a back-thinned and TE-cooled CCD sensor which results in high sensitivity, wide dynamic range (200,000:1) and low noise. Performance is further optimised with stray light correction.

Integral® System Software for Illumia Pro 2 UV Spectroradiometer
Labsphere’s Integral® software drives each Illumia Pro 2 UV sphere system, allowing you to operate your spectroradiometer from any device at any location and in multiple languages. Integral software also communicates with third party power supplies (AC & DC) as well as power meters, temperature monitors and the TEC temperature controlled mounting plate for the device under test (DUT). Integral redefines the way light is measured and revolutionizes how lighting measurements and control are synthesised into useful information. The innovative HTML5-based application software is for general lighting measurement control, test and reporting. The Application Program Interface (API) options were developed to work with your existing business software and product line integration.
