NORTH SUTTON, N.H., July 18, 2012 — 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 flux and color measurements in a 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 than simple illuminance meters using near cosine receivers. The ergonomic instrument measures both luminous flux and color 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 accurate results. The luminous flux range is 0.1 to 5000 lm, with a wavelength resolution of <5 nm and accuracy of <0.5 nm. Data is retrieved via USB connection to a laptop or PC and analyzed with proprietary MtrX-Spec software. The software calculates all industry-standard color parameters such as X, Y, correlated color temperature, color rendering index, lumens and spectral irradiance.
