Products > Light measurement > Micro LED measurement system > AL-1000


AL-1000 is designed for the brightness measurement of micro LED on chip and wafer. With its high sensitivity spectrometer, it measures ultra low brightness from 1μcd. It is ideal for the delicate application field from quality control to research and development.

  • Ideal for precise measurement of ultra-low light at 1μcd level by applying ultra-high sensitivity spectroradiometer

  • Traceable with KOLAS, JCSS and NIST

  • Works with SMU(Source Meter Unit)
