NIKON METROLOGY’s 750-kV X-ray source with micron level spot size is a high-power device for non-destructive inspection or measurement of large or dense objects, including engines, turbine blades, and large composite parts, with “unprecedented” resolution. According to the developer, it is the only 750 kV micro-focus source available that provides superior resolution and accuracy compared to traditional mini-focus sources.
Nikon Metrology X-ray sources are designed and manufactured in-house as the basis for its X-ray and CT technology. Expertise developed over 25 years allows Nikon Metrology to present innovative solutions as markets and applications require.
A critical element of the 750-kV X-ray source is a novel, high-speed rotating transmission target that allows the source to be operated at maximum power with a fine spot size.
The 750-kV micro-focus source features a spot size of 30 to 50 µm depending on the power, at least 10 times smaller than corresponding mini-focus sources. By integrating the high-voltage generator into the vacuum chamber, high-voltage cables and their associated problems are eliminated.
Thanks to its open-tube design with user-replaceable filaments, the source has a virtually unlimited lifetime with a low maintenance cost.
The 750-kV source targets NDT inspection and CT metrology of small and large turbine blades, precision high-density components used in high-temperature and/or high-pressure applications (e.g. turbo chargers, compressors, etc.), and automotive aluminum castings, as well as for Carbon Fiber-Reinforced Polymer (CFRP) components, such as helicopter or jet engine fan blades,
The source offers sufficient penetration power and accuracy for in-depth inspection.
Typical material penetration values are 160 mm for aluminum and 60 mm for steel.
