An industrial endoscope is a precision device, designed to withstand extreme conditions: high temperatures, dusty atmospheres, and corrosive environments. However, despite its robustness, it is not indestructible.
Even with thorough cleaning after each use, wear and tear is inevitable. Malfunctions can occur unexpectedly, and a visual external inspection is not always enough to detect early warning signs.
This is where the Cesyco workshop comes in: a timely return not only helps anticipate failures but also preserves optical performance and user safety. In short, it’s a long-term reliability guarantee.
When should you consider sending your endoscope back to the workshop?
Some warning signs should immediately alert the user. If you notice any of the following, it is strongly recommended to have your equipment checked:
-
The image remains blurry despite careful cleaning: this may indicate an optical failure or internal buildup that cannot be reached externally.
-
Presence of soot, burn marks, or oxidation visible on the sheath or around the lens.
-
Unusual ingress of water, air, or particles: often due to a loss of seal caused by worn-out joints or improper connections.
-
Visible wear, thermal shock, or suspected microcracks after use in particularly harsh environments.
In all these cases, a workshop inspection allows for an accurate diagnosis of the issue and a full restoration of the endoscope to optimal working condition.
What actually happens in the workshop?
A visit to the workshop is not just a routine check-up — it’s a targeted refurbishment, tailored to the real-world conditions in which the equipment is used.
Here are the main steps carried out by our specialized technicians:
-
Complete visual and optical diagnostic: inspection of the lens, sheath condition, connectors, and control box.
-
Thorough internal cleaning, especially of the optics, with re-polishing if necessary.
-
Electronic check (for digital models): testing of the camera, video signals, lighting, and proper functioning of buttons and connectors.
-
Inspection and cleaning of cooling circuits, whether air- or water-based. These channels can become clogged with invisible deposits.
-
Replacement of worn or damaged parts: sheaths, seals, viewing windows, lenses, cables, etc.
-
Final validation with performance tests, to ensure the endoscope is ready to return to the field without risk.
Why is this maintenance essential?
A return to the workshop is much more than just a repair — it’s a preventive measure, crucial for avoiding unpleasant surprises in the field.
Here’s what this maintenance provides:
-
Detection of micro-defects invisible to the naked eye, before they worsen.
-
Long-term optimal performance, even in harsh environments.
-
Reduced risk of inspection downtime during operations, thanks to equipment that delivers as expected.
-
Protection against progressive wear and damage: heat, dust, impact, corrosion…
-
Enhanced safety: a reliable endoscope also protects the technicians using it.
💡 Cesyco recommendation: for optical systems, we advise sending your endoscope to the workshop once a year, even if no visible symptoms are present, as part of preventive maintenance.
