Test Service

Thanks to our customers of the long year support, we decide to open our lab.

Any old or new customer, we can provide free test service for two times and issue the relative test report.

Test subject as below

Light source analysis test and Spatial intensity distribution test

1.       Light source analysis test

ItemCMS-3000S Spectroradiometer + integrating sphere test system

Testing environmentStandard optics lab .

The system includingSpectroradiometerIntegrating sphere,WL serial CC&CV DC Power sourceCHP Serial AC Power source,Digital Power meterStandard lampTraced to NIM ).


The system adopts the world advanced holographic concave gratin, precision optical system,the electronic shutter control technology and CCD linear array detector. It has low stray light, wide linear dynamic range, high repeatability, high stability, millisecond test speed and high accuracy.
