Normally small diameter endoscopes with articulation features are very expensive, especially the ones for medical applications. Sometimes, articulation of probe heads is not required. Here we provide a series of non-articulation borescopes with probe diameter from 0,78mm to 9mm. Some are rigid probe version, some are flexible version. Some have LCD display monitor, and some are USB version to be used on a PC or smart phones.
