Luminous Flux of Large LED Lamps and Luminaires

The GL Opti Sphere 2000 and 3000 were designed for the measurement of large LED luminaires and modules for luminous flux, radiant power and color. These systems enable LM79 compliant testing and also comply with the recommendations of the CIE Technical Committee published in the CIE 127:2007 Technical Report.

The size of the sphere and the side-opening system facilitate the easy installation of a variety of light sources using additional adapters or holders, allowing full measurement flexibility. As with all our integrating sphere systems, this system can be equipped with any of our high-performance spectrometers and powerful automation and analysis software to produce a completely turnkey system that anyone can operate.

Opti Sphere 2000 Usage

Measure. Launch. Grow.

With more and more companies manufacturing commercial lighting fixtures, there is increasing demand for a reasonably priced, accurate and easy to use solution to test & measure large luminaires during development and as a QC measure in production. The Opti Sphere 2000 integrating sphere was developed to meet this need and offers a completely turnkey solution for all your light measurement needs, big or small.

The Opti Sphere 2000 delivers exceptional luminous flux and color accuracy without the operational complexity associated with other photometric test equipment. A dedicated metrologist or large dark lab are not required. Setup the system and start evaluating your lamps in no time. Our customers appreciate that you can just open the sphere, install the lamp inside and measure. This sphere is equipped with all accessories and components you need and our GL Spectrosoft software interface will help you to do it right.

A Laboratory of your own

This instrument is equally suited to accredited laboratory environments, production labs or in R&D for quick quality control. When using external labs becomes too expensive or time-consuming, the Opti Sphere 2000 is an excellent choice for LM79 light measurement applications.

Instant customized Reports

Install, measure and prepare customized report directly from our GL Spectrosoft suite. This analytical software will control the measurement instrument, auxiliary light source and optionally manage peripheral devices like programmable and stabilized power supplies or TEC controllers. All these can be included in one complete measurement report.

Opti Sphere 2000 Features

Specially designed 660mm entrance aperture

Conforming to CIE recommendations, front emitting diodes can be measured at the wall entrance in 2π geometry while other types of LEDs or other sources with wider emission are measured at the center of the sphere in 4π geometry. The entrance of the sphere is equipped with a specially designed 660mm entrance aperture which can be used for calibration purposes. Additional accessories can be installed as required by specific measurement scenarios.

Auxiliary light source

To obtain top measurement accuracy, the GL OPTI SPHERE 2000 has been equipped with an auxiliary light source to compensate for self-absorbance of DUT’s.
