Rigid borescopes provide a significantly higher resolution image than flexible fiberscopes, or even videoscopes, due to their optical system construction that transports the image directly to the eyepiece. Their all-metal construction adds extra robustness and durability even in the most challenging conditions of an industrial inspection. A wide range of standard Rigid borescopes are available featuring various diameters, working length, viewing directions and angles. The stainless steel insertion tube is usable at temperature between 0°C and 60°C. They are also IP67 waterproof.
