Mini-Rigid Borescopes 

To facilitate visual inspection of minor components, products and units, borescopes with reduced diameters have been developed which are equipped with the excellent "High-Speed" rod lens system made by HSW. They are characterised by an excellent image reproduction, both in the centre and the peripheral zone of the view field. In this way, they facilitate inspection of small-size details in all industrial applications by rendering high-resolution, super-bright images.
