Normally available dilatometers of the series L75 which use the single/double push rod principle of measurement are successfully available in the market since 1957. As a further total new development Linseis is now offering a Laser Dilatometer built after the Michelson-Interferometer principle.

Unmatched resolution and absolute accuracy is now possible due to the new development of the Linseis Laser Dilatometer of the Pico-series. As the name indicates already the resolution goes up to Picometers (0,3nm = 300 Picometer). That means resolutions can be obtained which are up to a factor 33,33 higher as the resolution that were possible up to date. On top the principle of interference measurement give the possibility for much higher accuracy's, especially as some special computer calibrations are used. Up to now absolute accuracy's of 1% were normal, with best accuracy's up to 100nm. The new method allows accuracy's up to 30nm.
