If it is not possible to reach the inspection area using a rigid borescope, we recommend to use our flexible optical- fibre borescope. The inspection operation can be carried out with one hand. Moreover, the borescope tip can be bent 2way or 4way depending on the design type by means of a remote-control function from the main unit. This function allows to control both the insertion direction and the viewing direction. The image captured by the objective lens is distributed to many thousands of optical fibres, routed to the eyepiece where it is put together again to form a high-quality image.
