Utilising a non-contact laser displacement sensor, the OSP370 module allows fast
and accurate non-contact surface measurement to a very high accuracy. Features
of less than one micrometer can be imaged and measured over a height measurement
range of 10 mm without touching the sample surface.
The OSP370 incorporates a CCD displacement sensor mounted on the scanning head
of the M370 workstation. A small spot of laser light at 650nm is projected down
onto the sample surface and the scattered light is focused on to the CCD array
allowing the direct displacement measurement of the diffuse scattered light.
This allows very accurate surface height profile of the entire surface to be
generated and thus measurement the surface roughness and topography features.
Most importantly, the OSP370 module will allow the use of the generated data
subsequently to alter the height of the probe in any of the other
electrochemistry techniques, so the probe can scan over uneven surfaces whilst
maintaining a constant distance of the probe from the sample.
