Endoscopes

Purchasing advice for endoscopes

We stock various endoscopes for technical use, such as for building diagnostics or engine inspection. Here we describe what you need to look out for when buying an endoscope. You can find a detailed version of this article here. Eine ausführliche Fassung diesen Artikels finden Sie hier.

Rigid and flexible endoscopes: Rigid endoscopes are easier to guide, but cannot follow cables. Flexible endoscopes, often with a fibreglass neck and a sensor in the main device, are widely used in medicine. Video endoscopes for construction have the sensor in the probe.
Probe diameter: A critical factor that depends on the size of the opening into which the probe is inserted. Smaller diameters can have limitations.
Single or dual objective: Endoscopes with one objective provide only one line of sight, while those with two objectives have a switch for different viewing angles without having to remove the probe.
Movable probe: These endoscopes offer the greatest flexibility with a joystick, as the probe can be rotated in all directions.
Interchangeable probe: Some models allow the probe to be changed so that the basic device can be used for different applications.
Probe length: Depends on the application, although a length of around 120 cm is common.
Resolution: A decisive feature, whereby the specified resolution may deviate from the actual sensor resolution due to pixel interpolation. A full HD endoscope has 2 megapixels, which is sufficient for a 13×18 cm printout.
