BTS2048-VL Bi-Technology Sensor

What is a BiTec-Sensor?

The BiTec-Sensor (BTS) Joins Two Light Detection Technologies for Improved Overall Performance

 

 

The Bi-Tec Sensor is what makes Gigahertz-Optik's BTS series LED & light measurement instrumentation different from the competition:

  • Photometric V(λ) filtered integral detector is combined with a diode array spectrometer
  • The integral detector measures light intensity in absolute photometric quantities
  • The diode array detector measures the spectral distribution
  • The diode array's spectral data is used for on-line real time computational correction of the integral detector's spectral mismatch error as well as computation of other color and photometric quantities

The BTS employs the advantages of both detector technologies while minimizing the disadvantages in each.
