Mesurement of Luminous Flux - the

Integrating Sphere Adapter ISP 75

The ISP75 integrating sphere adapter is available for measuring

luminous flux and radiant power.

The LED test fixture is used to push the LED into the opening of

the sphere in such a way that the light radiation is captured by

the integrating sphere. The interior of the integrating sphere has a

highly reflective and diffusing white coating for this purpose.

All LED test fixtures from Instrument Systems can be used with the

integrating sphere.

The Mini-Goniophotometer

The Mini-Goniophotometer was developed to characterize the

spatial radiation pattern of LEDs. The high angular resolution of

0.06° means that precise measurements can also be taken of

narrow-angled LEDs. The integrated stepper motor control offers

an angular range of 90° to the mechanical axis of the LED. The

orientation of the LED in the phi axis can be manually adjusted for

four orientations (0°, 45°, 90° and 135°).

The standard measurement geometry corresponds to the

LED-B

configuration, i.e. the distance between the LED and the

detector is 10 cm with a detector area of 1 cm². The detector diameter

can be limited to 0.6 mm when measuring narrow-angled LEDs.

The Mini-Goniophotometer is controlled by the software

via an USB interface.

A special measurement mode of the SpecWin Light software

features the dialog for setting angular parameters. The radiation

pattern is displayed in either polar or Cartesian (xy) coordinates.

The test data obtained are stored in ASCII-text files and can be

easily imported into MS Excel
