The thinnest diameter flexible fiberscope (down to φ0.64mm). You can inspect inside narrow-diameter hole with 1mm or more diameter.

In some applications, the entry port size to the area of interest can be restricted and inserting a scope can be extremely difficult. This will often necessitate using an instrument of smaller diameter than conventional models.

These instruments have ocular focus to ensure that the individual operator’s eyesight is accommodated and can be attached to CCTV to allow the images to be permanently recorded. To illuminate the inspection area, any one of the Olympus light sources can be used.
