uLUM Luminous Flux Meter for LEDs

This bundle combines a high-performance photometric sensor with an integrating sphere to provide simple and accurate measurement of luminous flux in units of lumens (lm).  The sphere includes an input aperture plate with a standard 5 mm diameter port, and a blank port adapter which can be modified to accomodate LED package sizes up to 19 mm (0.75") diameter. The system realizes a 2p partial flux geometry (aka 'forward flux').

The system's luminous flux calibrations are programmed into the benchtop optometer. Measurement results are displayed by the optometer in units of lumens (lm), and digital data can be acquired directly via PC.

Specialized Solutions:

Many variations and extensions of this basic system are available; when combined with suitable accessories, this type of system can readily be adapted to make more complex tests and measurements, including:

• LIV characterization
• Pulsed-mode testing
