GPM-1200A Goniophotometer

According to the CIE and IEC standard test method for LEDs, it is dedicated to the measurment of single and combination LED'S electrical performance, photometric performance, distribution of beam and other characteristic parameters . Equipped with test grating and test camera obscura,the instrument can meet testing requirements in any environment .

Application range

 It is mainly applied to all the parameters'  measurement of single LED, reflected light, par LED etc.

Test mode

It rotates around C axis and γ axis to get the 3D light intensity distribution curve.
