An optical dilatometer, unlike a standard push rod dilatometer, can push up to the dilatometric softness of the specimen and is a non-contact instrument capable of measuring thermal expansions or sintering kinetics of any type of material.
a tool for measuring changes in a specimen’s dimensions; visually, the resolution gained can produce results that are better than those of a traditional pushrod dilatometer. The specimen is illuminated by a monochromatic light source, such as a laser. Optical interference fringes are produced when some of the light is reflected by the specimen and interferes with the incoming light.
A camera system can be used to measure the proportional movement of the interference fringes as the specimen compresses or expands. The measuring resolution, which is typically 0.5 m for blue light, depends on the wavelength of the light. Thermal expansion is assessed using optical dilatometers. is a tool for monitoring changes in a specimen’s size; optically, the resolution reached.
When it comes to measuring dimensional changes in materials as a function of temperature, the optical dilatometer is really complimentary to the conventional, better resolution push rod dilatometer because no contact between the specimen and the instrument is necessary.
The goal of dilatometry techniques is to determine how much a material’s volume varies with temperature. An instrument called a mercury-based dilatometer is typically used for these observations. The glass transition temperature is shown by a sharp change in the slope of the curve.
Global optical dilatometer market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
With a temperature range of -263 °C to 2800 °C, Linseis manufactures a variety of single, dual, differential, quattro, quenching, deformation, laser, and optical dilatometers. Their dilatometers have the highest level of accuracy and can measure the automatic length change of solids, powder pastes, and liquids.
Water Vapor L40/MV,Our analyzers allow us to control the variable concentration (in Vol.-%, wt.% or ppm) of the water vapour in the sample gas by mixing it with a carrier gas such as air, nitrogen, or helium.100% H2O atmosphere at the generator is possible because the generator evaporates water without necessary combining the leftover water vapour with other purge gases.
