Lumere GM (High Accuracy LED Test System)

Lumere GM is a LED test and measurement system (spectroradiometer) for various parameters of LED light. It is a high-accuracy system with a temperature-controlled CCD, its optical measurement conforms to CIE-Publication 127, and the test program is easy to configure and adjust.

The Lumere GM is used in laboratory applications and in the production of high-power LEDs. The system can be coupled with a baffle tube Condition A or B for luminous intensity measurement or an Integrating Sphere for luminous flux measurement. Standard sphere sizes of 8”, 6”, and 4”, as well as custom sizes, are available. A high-accuracy source meter is used to power the LED to perform all electrical test and measurement.

Lumere can be combined with LumereSoft software for the creation and adaptation of the test program and control of the Spectroradiometer and Source Meter. Different range of Source meter can be selected based on the requirement.
