FORT borescopes and fiberscopes are completely sealed at the distal end, and along the whole length of the insertion sleeve. The object lens and eyepiece use new types of very-low dispersion optical glass. The diameter of the fibres in the image conductor is less than 10µm. All functions can be controlled with one hand, and the small 90mm control lever avoids an unwieldy lateral offset. - Sealed - Diameter: from 2.7 to 10mm - Usable length: from 55 to 1200mm - Vision: 0°/30°/70°/90°/110° - Cost saving - High quality image
