Labsphere illumia®lite a World First in Portable Spectral Flux Analysis

Labsphere, Inc. has expanded its illumia LED and light measurement product range with the introduction of illumia®lite. The portable system packages the accuracy of sphere-based measurement in a cost-effective handheld device suitable for use on the production floor, in the lab or in the field.

• 4cm integrating sphere spectral light measurement system
• Measures LEDs and other sources up to 1 cm
• Wavelength range 380 nm – 820 nm
• Luminous flux range 0.1 lumens – 5000 lumens
• Wavelength resolution < 5 nm
• Wavelength accuracy < 0.5 nm
• Dark correction capability via software
• Self-absorption correction via built-in auxiliary lamp
• Device calibration capability
• Handheld portable size and weight
• Ergonomic design
• USB connection to computer with easy-to-use software

The illumia lite overcomes the drawbacks inherent in other handhelds by incorporating a spectrometer calibrated for absolute spectral flux and employs an integrating sphere in its design. This combination delivers more complete spectral flux measurement capability than simple illuminance meters using near cosine receivers. The ergonomic handheld instrument measures both luminous flux and colour of a device under test, including LEDs and other sources up to 1 cm in diameter. A built-in auxiliary lamp provides self-absorption correction for highly accurate results.

The luminous flux range of illumia lite is 0.1 lumens to 5000 lumens, with a wavelength resolution of <5nm and accuracy of <0.5 nm. Data is retrieved via USB connection to any laptop or PC and analyzed with Labsphere’s easy-to-use MtrX-Spec software. The software calculates all industry standard color parameters such as x, y, CCT, CRI, and lumens, as well as spectral irradiance.
