Tristimulus Colorimeter C-400

SSL Resource - Photometric Testing Efficiency

SSL C-400 Colorimeter is a quick and reliable measurement instrument. C-400 is used as a standard photometer in the small-to-medium size SSL goniophotometer testing systems and LightTester.

With the LabVIEW drivers, you can build your own test software.
