Measured & Displayed Profile ParametersRaw and smoothed profiles
Triangular running average filter up to 10% FWHM
Beam DiameterDiameter at two user set Clip levels
Gaussian & ISO 11146 Second Moment beam diameters
Equivalent diameter above a user defined Clip level
Equivalent Slit and Knife Edge diameters
Beam FitsGaussian & Top Hat profile fit & % fit
Equivalent Slit profile
Beam EllipticityMajor‚ Minor & Mean diameters. Auto-orientation of axes.
Centroid PositionRelative and absolute
Intensity Weighted Centroid and Geometric Center
Beam Wander Display and Statistics
Measurement Accuracy (not limited to pixel size)0.1 µm processing resolution for interpolated diameters.
Absolute accuracy is beam profile dependent - ~1 µm accuracy is frequently achievable.
Centroid accuracy is also beam dependent (as good as ±1 µ since it is arithmetically determined from all pixels above the centroid clip level).
Processing OptionsImage & profile Averaging‚ 1‚ 5‚ 10‚ 20‚ Continuous.
Background Capture and Subtraction.
User set rectangular Capture Block for capture
User set or Auto ellipse Inclusion region with beam tracking for processing
*.ojf files save all WinCamD custom settings for particular test configurations
Update Rates~5 Hz maximum for full frame‚ full screen. Higher for small Capture Blocks
Pass/Fail displayOn-screen selectable Pass/Fail colors. Ideal for QA & Production.
