ZWL-I5 model can test photometric colorimetric and electric parameters for checking the quality of LED chips.

Electric test: forward voltage andreverse current.

Photometric test: luminance LOPaccording to the different component can measure cd/mcd/W/mW/lm/λp,λd,λc,hw,purity,(x,y),CCT,CRI;

Four-wiretype test and touch resistance function avoid wrong judgement.

International authoritative standard:

Traceable with IS standard.

Morepowerful expandability to save the cost:

It canbe customized

ESD isoptional to reach human body model 4KV( maximum 8KV)

Luminousintensity detector or integrating sphere test is optional.

Probetest platform has a good compatibility.

Fasterand higher accuracy:

Singlechip test can be finished in 60msec (including polarity test, VF,IR,IV,λp and λd test)

OceanOptics spectrometer makes sure the stability of chromaticity coordinates isless than 0.0015.

ZvisionF4M technology integrating sphere supports 4π and 2π measurement with reflectivity over 98%.

The accuracy of reverse voltage is 0.1%+50mV;forward current is 0.1%+0.1mA; reverse leakage current is 0.1%+0.5μA.

Humanized software with good practical applicability:

Networkcommunication and supports one key calibration.

Support data inquiry, analysisand production capacity assessment.
