Applications

  • MWIR/FIR/CO2 laser profiling
  • Field servicing of MWIR/FIR/CO2 lasers and laser-based systems
  • Optical assembly & instrument alignment
  • Beam wander & logging
  • M2 measurement with available M2DU stage
Sensor Vanadium oxide (VOx) microbolometer
Wavelength Broadband MWIR/FIR: 2 to 16 µm
Pixel Count, H x V 307 kilopixels, 640 x 480

Pixel Dimension 17 x 17 µm
Min. Beam (10 pixels) ~170 µm
Shutter Type Rolling
Max. Full Frame Rate 30 Hz (7.5 for export)
Signal to RMS Noise ≥1000:1
Opt./Elec. dB 30/60
ADC 14-bit
Measurable Sources CW beams, pulsed sources (auto-trigger sync)
Measured Beam Powers See the Approximate Saturation Power Limits graph
Manual Beam Attenuation Provided 1″ ND-1 and ND-2 reflective Germanium filters. See app note for more info.
Displayed Profiles 2-D & 3-D plots
10, 16, 256 or max colours or grey. Contoured display at 10 and 16 colour.
Measured & Displayed Profile Parameters Raw and smoothed profiles
[Triangular running average filter up to 10% FWHM]
Beam Diameter Diameter 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 Fits Gaussian & Top Hat profile fit & % fit
Equivalent Slit profile
Beam Ellipticity Major, Minor & Mean diameters. Auto-orientation of axes.
Centroid Position Relative and absolute
Intensity Weighted Centroid and Geometric Centre
Beam Wander Display and Statistics
Measurement Accuracy 5 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 Options Image & 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 display On-screen selectable Pass/Fail colours. Ideal for QA & Production.
Log data and statistics Min., Max., Mean, Standard Deviation, to 4096 samples
Relative Power Measurement Rolling histogram based on user’s initial input. Units of mW, µJ, dBm, % or user choice (relative to a reference measurement input)
Fluence Fluence, within user defined area
Certification RoHS, WEEE, CE
Multiple Cameras Up to 4 cameras, parallel capture.
1 to 8 cameras, serial capture.
