LED total power Test System
MODEL 58173
The Chroma 58173, in automatic operation, comes
with unique design and a whole new method for
LED total power measurement. In bare wafer/chip
LED test production, partial flux correction of
total flux is the common measurement method in
LED epitaxy industry. (See Figure 1 on flip page)
However, conventional method causes some
disadvantages, i.e., lower accuracy, low S/N ratio,
and slow test time etc., and which are difficult to
be applied on LED bar wafer/chip total power/flux
test production.
Chroma has developed a high speed and high
accuracy measurement method of LED total
power/flux. (See Figure 2 on flip page) Appling
this innovative test method enhances to gather
more LED partial flux than using the conventional
method. (See Figure 1 on flip page) It improves
the accuracy dramatically and significantly.
Benefited Chroma's unique optical and mechanical
design, LED total radiant flux will be collected by
a wide photo detector. Other optical features like
dominant wavelength, peak wavelength, CCT, etc.
will be detected by Chroma's spectrometer. In
addition, the 58173 offers a 6-inch wafer chuck
and a packaged LED holder which users can
collect variety of samples in one station. With
a wide range of power source and meter, users
can gather all of LED electrical data like forward
voltage, leakage current, and reverse break voltage
in one test step.
