Model : APA-AT

Description :

Automatic LED Profile Analyzer is a comprehensive and self-integration development LED Profile Analyzer. The main design of the multi-functional integrated Analyzer is providing user the optical data and figures of measuring and analyzing, such as total luminous flux, luminous intensity, spectroradiometry (emission spectrum, chromaticity coordinates, dominant wavelength, FWHM are included) and the data of 2D/3D light intensity distribution ...etc. Those information can be applied on the parameters designed andverificated.

Using CCD(Charge Coupled Device) to do the alignment with automatically rotation stage which contains an encoder. It can achieve high-accurate angle control and enhance the precision of measurement. According to the LED light property and contacted surface temperature, we add on a Thermoelectric Cooling Module to control the temperature of LED substrate. To make sure the stability of LED in the measurement process and to achieve the purpose of accurate measurement, it provides the relevant optical characteristics of LED at different temperature of substrate.

Besides the standard stage which supports the standard Star substrate, 2cm square substrate and LED Emitter, we provide the customized service.
