Extendable borescopes with warm light illumination

The borescopes have been laid out for inspecting long components and work devices or bridging major distances. Typical applications are pressure tanks, pipes, steam boilers, large-size diesel engines or helicopter rotor blades. Borescopes of this type can be extended by means of extension tubes (Ø 24 mm) up to a length of 30,000 mm. High-performance halogen lamps of a compact design (low voltage) integrated in the replaceable objective lens head provide for optimum brightness throughout the inspection area.
