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.

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 <0.5nm. Data is retrieved via USB connection to any laptop or PC and analysed with Labsphere's easy-to-use MtrX-Spec software. The software calculates all industry standard colour parameters such as x, y, CCT, CRI, and lumens, as well as spectral irradiance.
