L74 / Heating Microscope

Heating Microscope (DIL Dilatometer)

L74 / Heating Microscope

The Linseis L74/HM (Heating Microscope) optical dilatometer offers fascinating real-time video investigations not available in any other heating microscope / dilatometers.
Imagine resolving details down to the micron scale over a large field of view (10mm x 14mm) at data sampling rates of up to 10s points per second.
This capability makes it easy to measure sintering shrinkage, creep, melting behavior, volumetric change and contact angles in real time.


New application areas can now be tackled over a broad temperature range (-150 to 2000°C) in a vacuum tight design with gas handling capabilities.
Our robust instrument software allows automatic evaluation of videos and images, including automatic determination of wetting /contact angles and viscosity temperature points.
Compatible with the following standards DIN 51730, ISO 540 or CEN/TS 15404. 

The main advantages of the heating microscope are:

  • Contact free measurement of samples
  • CTE of solids and volumetric change of melts
  • Instrument capable of multiple atmospheres.
  • Broad temperature range from -150°C to 2000°C
  • Automatic evaluation of relevant temperature points
  • Video and image recording in real-time
  • Optical optimization packages available for CTE and optical microscope (separate or combined)
