    Detector Responsivity Measurement System

    Photodetector is the sensor that could convert the optical radiation signal to the electrical signal, which is made from photoemission material. Most of the photodetectors have strong spectral selectivity in a certain Spectrum area. Therefore, for one photodetector, different wavelengths have different spectral responsivity. The spectral responsivity is an important parameter index for characterizing the photodetector performance.
    And for the photoelectric material researching , the effect of some characteristics of the material itself such as doping density, lattice imperfection, absorption coefficient and minority carrier diffusion length on the photoelectric response capacity and the quantum efficiency could be obtained by measuring and analyzing the spectral responsivity data. That is very important and helpful for choosing better material and processing improvement.

    System Benefits

    ◆Wide wavelength range (200~14000 nm, optional), widely applicable
    ◆Turnkey system, Easy maintenance.
    The system uses substitution method of measuring principle, which is designed into Turnkey mode. Users do not need to debug the system before experiments. Routine maintenance is also very simple.
    ◆CCD monitoring optical path for sample location. The detectors with very small area can be located precisely by the system.
    ◆perfect reflection optical design, optimization of spot quality
    the perfect reflection optical system, you can get the quality parallel spot or much small convergency spot.

    ◆High stability light source, reducing the background noise.

    ◆Data export format supports third- party software.
    DSR100 can save all original data, and the experimenter can save the data as the *.txt, *. *.xls* and so on.
