  • Introduction to the detectors techniques - HORIBA

    These detectors are most commonly used for steady-state measurements, but in certain cases, when coupled to a fast amplifier, may also be used for time-resolved measurements. When two detectors cover a similar wavelength range, such as InGaAs and Ge, the choice is based on gain, noise factors and response at a specific wavelength of interest.
