| 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 |

Background Capture and Subtraction.
User set rectangular Capture Block for capture
User set or Auto ellipse Inclusion region with beam tracking for processing
