In high-temperature industrial environments, visual quality is a key factor in ensuring safe and reliable inspections. At CESYCO, this performance is made possible by interchangeable camera heads, each custom-designed to meet the specific constraints of our clients. Manufactured from Onyx — a high-performance composite made of nylon reinforced with carbon microparticles — these heads deliver optimal optical precision while withstanding ambient temperatures up to 60 °C. With carefully selected viewing angles, fields of vision, and optical directions, our endoscopes adapt to even the most complex conditions — whether confined, dark, or exposed to extreme stress.

Vision directions – Axially, laterally or bi-vision?

Axial view (0°): Direct observation of what’s in front of the endoscope. Ideal for inspections of deep cavities or straight channels.

Axial view

Side vision (90°): Observe walls or side areas without tilting the device. Perfect for wall or internal surface inspections.

vision latérale 90°

Bi-vision: Allows simultaneous axial (0°) and lateral (90°) observation, for a complete view of the oven interior and walls. Capture photos and videos from multiple angles effortlessly, for more precise and efficient inspection.

Angles of vision – For the right perspective

Viewing angles direct the endoscope’s gaze in the desired direction, without the need to move the device:

  • 0° (axial): Straight, direct vision.
  • 20°, 45°, 65°, 90°: Adapt to complex geometries.
  • 110°: Used for extremely offset or panoramic views.

Field of vision – Width or precision?

  • 60°: Narrower, but deeper field of view. Ideal for targeted vision, useful for detecting precise defects or inspecting a strategic point.
  • 90°: Wider field of view, enabling coverage of a large area in a single shot. Recommended for global surface checks or large-area surveillance.

  • Axial LED: Illumination in the line of vision, essential for inspecting deep areas.
  • Lateral LED: Illuminates walls or off-center areas.
  • Optimized visibility: LEDs reduce shadows, increase contrast and ensure a sharp image, even in very low light conditions.

Conclusion :

The performance of an industrial endoscope relies not only on its resistance to high temperatures or its image transmission technology — it also critically depends on its ability to see exactly what needs to be seen, exactly where it matters. At CESYCO, we have made vision a core focus of our development, designing custom-made camera heads optimized for every inspection scenario. Through precise control of angles, fields of view, optical directions, and lighting, our solutions adapt to the specific constraints of each environment — whether it’s monitoring a burner, observing refractory walls, or tracking the flow of materials

This refined, tailored approach allows us to effectively support our clients across all demanding industrial sectors, ensuring impeccable image quality… even in places the human eye cannot reach.
