Touch probe adds new dimension to measurements
Adding 3D contact measurement to noncontact optical and laser measurement makes the Nikon iNexiv VMA-2520 system a truly compact multisensor machine.
System checks component quality
DNTR will be using an iNEXIV VMA 2520 video measuring system to make rapid checks on the quality of bought-in metal and plastic components
Applications for its patented range of actuators include: a miniature autofocus control for tiny CMOS cameras that fit into mobile phones and coil-less loudspeakers, again suitable for communications devices but offering amazing MP3 quality sound.
Development of the patented Helimorph ceramic actuators is carried out at the company's Cambridge manufacturing facility.

Metrology microscopes automatically correct errors
The MM400/800 series of manual metrology microscopes offers through-the-lens laser autofocus (TTL Laser AF), automatic edge detection and white LED illumination.
Measuring system provides rapid QC checks
Nikon Instruments' iNexiv VMA-2520 is ideal for rapid QC checks and demanding RandD work on mechanical, pressed metal, plastic moulded parts, as well as medical devices and electronic components.
This is used to assist engineers in documenting product development progress and achieving exactly the right format for the miniature ceramic coils, which can measure just a few millimetres across.
The highly versatile microscope is invaluable for checking the bonding of ceramic PZT material to metal electrodes, the porosity of samples and highlighting cracks or defects in the material, which could lead to premature product failure.
The microscope is also used to obtain critical measurements for ongoing manufacturing and further development of the actuators.
Its ability to measure down to sub-micron accuracy is invaluable for the high precision work.
The Nikon MM40 microscope was supplied with a PC running Lucia software under Microsoft Windows and equipped with a DXM1200 digital camera - used to record and store digital images of the various stages of development.
The linked PC also holds an Access database currently containing over 1300 records, which will ultimately assist in refining the final manufacturing process.
Dr Mark Swetnam runs the development laboratory, "We chose the Nikon MM40 because of its versatility, ease of use and ability to adapt to a wide range of sample sizes.
The Lucia software allows us to take a number of non-destructive measurements, while the DXM1200 digital camera enables capture and storage of valuable images to highlight flaws and accompany our Access database." Mark added, "It was important to have a rugged unit with inherent stability and a large, easily movable stage to allow for larger samples - some of which can be up to 50mm in size." In summary Dr Swetnam reported that the installation of the microscope system was trouble-free and a couple of in-house training days soon had all members of the laboratory team fully familiar with the measurement software and day to day operation.
Thanks to 1Limited's detailed microscopic view of the developments, the future of hi-fi videophones seems to be just around the corner. Request a free brochure from Nikon UK ...
