Normally available dilatometers of the series L75 which use the 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. The original push rod dilatometer is based on a development made by Dr.Max Linseis in the early 1950th. In those days the principle used was the same as today, using a measuring tube in which the sample is placed. The expansion signal of the sample is transmitted through a push rod onto a LVDT sensor (linear variable...

A further increase of resolution, as well of the absolute accuracy is now also possible through the new development of the LINSEIS Laser Dilatometer of the Pico-series. As the name indicates already the re- now absolute accuracy• s of 1% were normal, with best accuracy• s up to 100nm. The new method allows accuracy• s up to 30nm.
