Measurable SourcesCW beams, pulsed sources with external synch
Measured Beam PowersTBA
Manual Beam AttenuationIncludes ND-1, ND-2, and ND-4 C-mount ND filters
Displayed Profiles2-D & 3-D plots
10, 16, 256 or max colors or gray. Contoured display at 10 and 16 color.
Measured & Displayed Profile ParametersRaw and smoothed profiles
[Triangular running average filter up to 10% FWHM]
Beam DiameterDiameter at two user set Clip levels
Gaussian & 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 Accuracy5 µm processing resolution for interpolated diameters
Absolute accuracy is beam profile dependent - ~10 µm accuracy is frequently achievable
Centroid accuracy is also beam dependent. It can be as good as ±10 µm since it is arithmetically derived 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
Pass/Fail displayOn-screen selectable Pass/Fail colors. Ideal for QA & Production.
Log data and statisticsMin., Max., Mean, Standard Deviation, to 4096 samples
Relative Power MeasurementRolling histogram based on user's initial input. Units of mW, µJ, dBm, % or user choice (relative to a reference measurement input)
