For viewing and/or inspecting into extremely small, straight, restricted areas, ITI Rigid Micro Borescopes feature gradient rod lenses that produce exceptionally clear images. Unlike regular lenses that depend on lens curvature and glass index for image formation, gradient rod lenses form images through a variable (gradient) glass index.

For applications that require greater stamina or longer working lengths than standard rod lens Rigid Micro Borescopes provide, ITI’s Semi-Rigid Micro Borescopes provide the practical, workable solution by combining the protective stainless steel outer tube of a Rigid Micro Borescope with the high resolution fused image guide of a Semi-Flexible Micro Fiberscope.

Precision, high image quality is an ITI mark of distinction. Because optimal resolution is based on the tightest pixel density, ITI uses the best fused image guides possible. In the process of manufacturing, glass fibers are drawn to the smallest diameter possible, packed to maximum density, then fused back together for structural strength. Maximum density is therefore achieved, resulting in highest possible image quality in a semi-flexible image guide.
