The LFA 457 MicroFlash® is the most modern product for the determination of the two thermophysical properties, thermal diffusivity and conductivity, in the range from -125°C to 1100°C. Its compact, vacuum-tight construction, automatic sample changer and functional software guarantee the highest effectiveness for challenging materials testing.
The NETZSCH LFA 457 MicroFlash® complies with the latest technology for modern laser flash systems. The table-top instrument allows measurements from -125°C to 1100°C using two different user-exchangeable furnaces.
The innovative infrared sensor technology employed in the system enables measurement of the temperature increase on the back surface of the sample, even at temperatures of -125°C.
The instrument can be used for small and large sample sizes of up to 25.4 mm diameter and, with the integrated sample changer, measurements can be run on several samples at the same time.
The vacuum-tight design enables tests under defined atmospheres.
The vertical arrangement of the sample holder, furnace and detector simplifies sample placement and, at the same time, guarantees an optimum signal-to-noise ratio of the detector signal.

Laser Flash technique over the broadest temperature range
Thermal conductivity and thermal diffusivity are the most important thermophysical material parameters for characterizing the thermal transport properties of a material or component. The Laser Flash technique is currently the most widely accepted method for precise measurement of the thermal diffusivity and the LFA 427 is the number one instrument on the world market.
High precision and reproducibility, short measurement times, variable sample holders and defined atmospheres are outstanding features of LFA measurements over the entire application range from -120°C to 2800°C.
A special version with a pyrometer allows measurements from room temperature to 2800°C.
The thermal conductivity of disk-shaped samples of ceramic, glass, metals, melts and liquids, powders, fibers and multi-layer materials ranging from vacuum insulation panels to diamonds is measured with equal speed and accuracy. The temperature-dependent measured thermal diffusivity value along with the corresponding specific heat (DSC 404 F1 Pegasus®) and density (DIL 402 C) data are used to calculate the thermal conductivity.
The laser power, pulse width, gas and vacuum are variable over a wide range, making it possible to set the optimum measurement conditions for the very different sample properties.

The LFA 467 HT HyperFlash® allows for accurate thermal diffusivity and thermal conductivity measurements between RT and above 1250°C with the smallest footprint on the market. The Ultra-fast sampling rate and extremely short pulse widths enable measurements of thin and highly conductive materials.
Accurate thermal diffusivity and thermal conductivity measurements between RT and above 1250°C with Xenon Flash
LFA 467 HT HyperFlash® is based on the already-established LFA 467 HyperFlash® technology and requires no laser class due to the innovative light source system. The long lifetime of the xenon lamp provides cost-effective measurements above 1250°C without costly consumables.
ZoomOptics – For precise measurement results by an optimized field of view
The patented ZoomOptics system (patent no.: DE 10 2012 106 955 B4 2014.04.03) optimizes the field of view of the detector, thus eliminating any influences caused by aperture stops. The result is a significant increase in the precision of the measurement results.
Ultra-fast sampling rate (up to 2 MHz) and extremely short pulse widths (up to 20 µs) enabling measurement of thin and highly conducting materials
The data acquisition rate of the LFA 467 HyperFlash® series was increased to 2 MHz. This acquisition rate applies to both the IR detector and the pulse mapping channels. Thereby, highly conductive and/or thin materials requiring very short test times can be reliably tested.
When testing metal (0.3 mm) and polymer foils (30 µm), an optimum sampling rate and pulse width can be selected. The patented pulse mapping system accounts for the finite pulse width effect and heat losses (patent no.: US7038209 B2; US20040079886; DE1024241).
Vacuum-tight for defined atmospheres and prevention of oxidation
An internal pump device supports defined atmospheres by an automatic evacuation function prior to each measurement. Additional connections for external pump devices are available. The vacuum-tight platinum furnace allows for heating rates up to 50 K/min.
High throughput and precision – 4 samples 4 thermocouples
Effective sample throughput over the entire temperature range is guaranteed by the automatic sample changer (ASC). Each of the ASC’s four sample positions is equipped with its own thermocouple. This results in drastically minimized temperature deviations between the sample and temperature measuring position. The ASC is designed for sample dimensions of 12.7 mm (round) and 10 mm (round and square).
All accomplished while still possessing the smallest footprint
LFA 467 HT HyperFlash® is the first flash lamp-based LFA system to reach temperatures above 1250°C. One single furnace with an integrated sample changer covers the entire temperature range, providing the small footprint that the LFA 467 HyperFlash® series is well-known for. Even at such elevated temperatures, an efficient internal water cooling circuit keeps the temperature of the surrounding components within a safe range, thereby reducing the liquid nitrogen consumption of the IR detector....

Sample throughput up to 4 times higher due to sample holder for 16 samples
One unique advantage of the LFA 467 HyperFlash® is its ability to simultaneously measure up to 16 samples over the entire temperature range. This allows for maximum sample throughput with a minimum input of operational time and effort.
Refill systems are available for automatic refilling of the Dewar on both the detector and the furnace, allowing uninterrupted operation of the LFA system around the clock.
