Fiber optic end-face inspection
Count and grade scratches and defects by zone on a connector end-face, per IEC 61300-3-35.

Example outputs shown for illustration. Numbers depend on your samples and protocol.
Results
Each measurement below comes from your own images, tied back to the annotated frame it came from, so results stay comparable across samples, locations, and conditions.
count or µm
Scratch count by zone
Visible surface features detected, measured, and located against the reviewed image.
In your report: Per-feature list with size, position, and annotated overlays.
µm or count
Defect count by zone
Size and shape measured for every detected object, then summarized across the population.
Example, not a claimed result
In your report: Per-object table, size distribution, and summary percentiles.
per area
Zone A/B/C/D pass/fail
Findings placed in sample coordinates to reveal spatial patterns and local density.
In your report: Coordinate-referenced map, regional density, and representative images.
per area
Sized feature list
Findings placed in sample coordinates to reveal spatial patterns and local density.

Built around your image set
Use the calibrated images your team already collects, together with the locations you need to compare.
Each report includes
The artifacts your team receives, ready for review and archive.
Annotated image set
Original images with regions of interest, measurement points, masks, and finding overlays.
Measurement table
Location-indexed values, units, distributions, and QC flags in a structured export.
Method record
Calibration evidence, analysis settings, version history, and validation summary.
Confidence in every resultTraceable measurements, reviewed against your agreed reference method.
- Traceable scale
- The report records the image scale, calibration evidence, and a method-specific expanded measurement uncertainty. It does not use one product-wide accuracy number.
- Reference comparison
- The configured method is compared with your accepted reference method or reviewed annotations, and reports bias by measurement range and image condition.
- Detection performance
- Detections are evaluated against reviewed reference regions with precision, recall, and segmentation overlap, separated by the conditions that affect performance.
- Repeatability
- The locked protocol is rerun on the same inputs and on a defined repeat set. The review records variation from image acquisition, sampling, and analysis separately where possible.
What this result does not establish: Applies the IEC 61300-3-35 zone-and-size counting rules to the end-face image. Pass and fail thresholds vary by connector type; select the ruleset that matches your connector.
The measurement, today
End-face grading is a technician looking down a scope and making a pass or fail call. The zone boundaries and the size thresholds live in their head, and the result is not logged with the image.
What it costs
A scratch across the core or debris on the contact zone raises insertion and return loss, which surfaces later as a link that will not certify. Re-terminating in the field costs far more than catching it at assembly.
From image to reviewed result
- 1
Image the end-face
Load an inspection-scope image of the polished connector end-face.
- 2
Register the zones
The four concentric zones (core, cladding, adhesive, ferrule) are placed on the fibre.
- 3
Detect and size
Scratches and defects are separated and measured within each zone.
- 4
Apply the criteria
The per-zone count-and-size rules give a pass or fail for every zone.
