Light distribution measurement system
The emission of devices like organic LEDs or other light sources varies strongly with the viewing angle. For proper characterization of such samples it is therefore necessary to measure brightness, chromaticity and the emission spectrum for different detection angles. Hamamatsus C9920-11 Light distribution characteristics measurement system meets these needs by using a rotating stage as sample mount and a highly sensitive detector.
|Rotating stage||Minimum angle setting 1°|
|Angle setting range||0 ° to +80 °, -80 ° to +80 °|
|Minimum step setting||1 °|
|Resolution||0.1 ° or less|
|Detector||BT (back thinned) cooled CCD|
|Cooling temperature (CCD)||-15 ℃|
|No. of photosensitive device channels||1024 ch|
|Wavelength measurement range||380 nm to 780 nm (detector: 200 nm to 950 nm)|
|Fiber probe||1.5 m|
|Measurement spot size||200 μm|
|Range for brightness measurements||10 cd/m2 to 10 000 cd/m2|
