Luminous flux of LED modules and luminaires

The GL OPTI SPHERE 1100 integrating sphere system fulfills the recommendations of the CIE Technical Committee, which are published in the CIE 127:2007 Technical Report, and is intended for the measurement of radiant power and luminous flux of large LED modules, mid-size LED luminaires, and other light sources. For expanding LED lighting producers without the room or funds for a 2M or 3M sphere, it is the perfect answer.

This comprehensive and user-friendly integrating sphere system complies with American LM79, CIE S025, and other international standards. With full measuring flexibility that complies with CIE guidelines, the GL OPTI SPHERE 1100 boasts a side-opening design that makes it simple to attach a range of light sources. The GL OPTI SPHERE 1100 can be combined with any of our spectrometers and software tools, just like all other integrating sphere alternatives, to provide the measurement system you require.

Mount and measure

This integrated sphere system has a mechanical stage by default that can be modified to mount a variety of fixtures and LED module types. It is simple to install various A-type goods thanks to an optional lamp post that is positioned in the center of the sphere. The software can automatically identify and connect any of our high-performance spectrometers to the sphere. Just load the light and leave the rest to the program.

Adaptable to your needs

You can choose from a variety of spectrometers and accessories for the GL OPTI SPHERE 1100 to acquire the finest features and spectral range for your needs, both technically and financially. This, along with our robust GL SPECTROSOFT software and GL AUTOMATION add-on, creates a fully functional test station that is simple to operate and allows anyone to get precise, repeatable results.

Accelerate product development

Because of its compact size, this integrating sphere system may be mounted on an office or production floor, giving engineers and R&D teams the ability to test lighting components on-site with speed and accuracy. Long lead times result from sending components and bulbs for laboratory testing, which eventually slows down the development cycle. These days, the findings are accessible right away when fresh boards are manufactured or new fixtures are delivered.


Measure, launch, and grow.

The market for LED retrofit lamps is growing quickly, and testing and measuring small to medium-sized LED lights needs to be done quickly and with accuracy. Everything from LED modules to tiny strip lights and downlights. To address this demand and provide comprehensive optical assessment of LED retrofit and replacement bulbs, the GL OPTI SPHERE 1100 integrating sphere system was created.
The remarkable luminous flux and color accuracy that the GL OPTI SPHERE 1100 integrating sphere system can provide are possible without the operational complications that come with other photometric test equipment. It is not necessary to have a large, dark lab or a dedicated metrologist. In little time at all, set up the system and begin assessing your lighting. The fact that you can simply open the sphere, place the lamp inside, and measure is appreciated by our customers. This sphere has all the parts and accessories you require, and the GL SPECTROSOFT software interface will assist you in doing the task correctly.

A laboratory of your own

For efficient quality control, this integrating sphere system works well in production labs, authorized laboratory settings, and R&D. When stepping into the world of professional testing and measurement, the GL OPTI SPHERE 1100 is a great starting point—especially when using external labs becomes too costly or time-consuming.

Instant customized reports

Install, measure, and use our GL SPECTROSOFT package to create customized results right away. The measurement tool, an additional light source, and optional peripheral devices like TEC controllers or programmable and stable power supplies will all be managed by this analytical software. These can all be found in a single comprehensive measurement report.

GL OPTI SPHERE 1100 Features

Side-opening system

Complete measuring versatility is made possible by the integrating sphere’s size and the side-opening mechanism, which make it simple to insert a range of light sources with the help of extra adapters or holders.

High durability and low weight

Front-emitting diodes can be measured in 2π geometry at the wall entrance in accordance with CIE standards, while other sources of light with broader emission can be measured in 4π geometry at the center of the sphere. The composite material used to make the integrating sphere ensures both low weight and great durability.

Specially designed 168mm entrance aperture

A 168-mm entry aperture that was specifically created for the integrating sphere’s entrance can be utilized for calibration. Specific measurement conditions may require the installation of additional gear. The GL OPTI SPHERE 1100 contains an additional light source to counteract the test LED’s self-absorption effect and provide optimal measurement accuracy.
