  Aperture Bound tester  KO-300




* Measures a diaphragm operating time and an error of a diaphragm.
Time until it goes into the range of the iris diaphragm specified from the trigger (ms), And the iris diaphragm error (ΔEV) of the specified time (time to be stabilized) is analyzed, A digital display is carried out.
Drive a diaphragm from the outside.(optional)
Measurement with various postures is possible.
Specifications
Measurement Subject Lens containing an iris diaphragm
Measuring item
Refer to measurement chart
T1(ms) Time until bound reaches a fiducial point from an external trigger
T2(ms) Time until bound settles down from an external trigger
ΔEV(FNo. eroor) FNo. error after T3ms (stable point) since external trigger
FNo. indication Indicates standard FNo. of FNo. error(ΔEV)
Has MANUAL and AUTO mode
