Model : J140413

Description :

Measure the light intensity distribution and total luminous flux of the sample light source with rotated lamp. It can be used to measure the spectrum of each space of the light source, chromaticity coordinates, color temperature and color rendering index when a spectrometer is added. The machine can output IES files which can be applied to optical design simulation software.

The testing item include vertical profile, Cartesian coordinate figure, 3D luminous intensity distribution curve, beam angle...etc.

• Chinese Interface, easy to use
• Full-automated measurement
• IES format output
• Optional with V(λ)sensor or spectrometer
• Customized hardware and software are available
