OSK21TB105 Strobe light distribution tester

Strobe light distribution tester
Application
        It measures how much amount of the light can be distributed by the camera's flash
Features
    1. Strobe light amount of 9 points strobe flash (GN,Ix・s, AV, Fno)and light distribution measurement
    2. Measurement distance is set in the range of は0.1[m]~9.9[m]
    3. It can display the light distribution in 8 points by ⊿EV or % using central light as its base
    4. Sensor part uses PIN photo diod for the correction of luminous sensitivity
    5. Maximal brightness measurement
    6. Light emission time measurement
    7. Can be applied to LED strobe as its option (STB-209LD)
      (Low brightness 5[lx] Measurement・GN0.1Measurement)
Effect
    1. Light receiving part is magnet adhesion type so its installation and movement are simple
    2. Settings, display and data processing can be easily done at PC
