EX2 V2*
The spectrometer that we use in most of our LED devices is also available as an external measuring device, the EX2 V2. The first version of the EX2 had two devices, one for the visible spectrum and one for the IR spectrum. The second version of the EX2 combines both the visible and IR spectrum into one device. It has a more comprehensive spectral range of 200 – 1100 nm (Irradiance calibration: 305 – 1100 nm), ensuring that it covers both spectrums.
The EX2 comes entirely NIST traceable calibrated and includes user-friendly software that can import the spectral distribution of a light source into your LED device and reproduce it in a matter of seconds.
Delivered product includes an attached USB cable.
