Surface Metrology

The Surface Metrology section is housed in the Nanolab which is the most advanced laboratory of it's kind in the UK. The equipment is capable of measuring to sub nanometre levels and has been used in a diverse range of applications including MEMs, Biomedical and Ballistics.The staff within the centre are constantly developing the equipment and related software to further enhance the capabilities within our laboratory.

The instrumentation consists of Optical Interferometry, Atomic Force Microscopes, and Precision 3D Contacting Stylus Profilometer giving the capability to measure areas up to 50 x 90mm whilst still being able to resolve surfaces at the nanometre level.

Techniques are available to replicate surfaces of components which are too large to be placed on the instruments.

	Talysurf PGI Stylus Measurement area: 50 x 90 mm Lateral resolution: 1.25 mm Vertical range: ±5 mm Vertical resolution: 4 nm
	Taylor Hobson CCI 3000 Measurement area:0.36 mm2 to 7.2 mm2 Lateral resolution: 0.36 μm to 7 μm Vertical range: 10 mm Vertical resolution: 0.01 nm
	Veeco DME Dimension Measurement area: 230 nm2 to 40 mm2 Lateral resolution: 0.2 nm to 2.5 mm Vertical range: 10 nm Vertical resolution: 0.01 nm
