Features of WinFTM BASIC and LIGHT
2.8 Optical Functions
Function Description
Video image of the speci-
men The specimen is shown in the video window inside the WinFTM
main window.
Scaled crosshairs Scaled crosshairs are electronically inserted into the video image.
They show the real size and position of the measurement spot on
the surface of the specimen. The color of the crosshairs is selecta-
ble.
Auto-focus (on models with
motor-driven z-axis) The detector unit moves up and down automatically. The auto-fo-
cus function allows a significantly more precise setting of the meas-
urement distance than subjective manual focusing. Thus, the
reproducibility of the measurement result is increased.
Measurement of the dis-
tance between the test spot
and the detector / DCM
method Focusing the video image provides the correct measuring distance.
WinFTM takes into account these distance values, when comput-
ing the coating thickness measurement data, using the DCM Meth-
od (Distance Controlled Measurement).
This allows for automated testing of complex surface geometries
and measurements in recesses.
Displaying programmed
points in the video image
(on models with motor-driv-
en XY-stage) You can display programmed points in the video image.
Software-based video
zoom function You can zoom the video image in steps of 100, 200, 300 and
400 percent. Additionally, you can display the video image in full
screen mode.
Saving video images to-
gether with the measured
values You can edit the video image with a graphic program of your
choice e.g. for adding comments or dimensions. When you save
the video image, it will be assigned to your measured values. Ad-
ditional text notes will be stored, linked to the video image.
Recognition of vertical or
horizontal strips (on models
with motor-driven XY-stage) The instrument can recognize strip structures on specimens and re-
adjust the XY position along this structure. Thus, you can make sure
that on specimens with geometric tolerances, the measurement is
always performed at the correct position.
Image/Pattern Recognition
(on models with motor-driv-
en XY-stage and WinFTM
extension SUPER activated)
The instrument can recognize a predefined structure and readjust
the XY position of the XY-stage along this structure automatically.
Thus, you can compensate deviations in positioning during meas-
urements on more specimen (e. g. for routine tests in production).
