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