Two user-interchangeablefurnaces are available for the LFA 457 MicroFlash Industrial furnaces Laser The Nd-glass-laser, with amaximum pulse energy of 15 J and a pulse length of 0.33 ms, is based in the bottom part of the instrument. The power output is controlled by the software and can be easily adjusted to the required application. The laser is connected to a sophisticated interlock system allowing the laser to fire only when the entire system is fully closed (Laser Class 1). A wide range of differentsample carriers for circular or square solid samples be- tween 6 and 25.4 mm are available. Sample holders for special geometries are available upon request. Of course, sample carriers for tests on laminates, fibers, pastes and liquids are available, as well. Sample carriers Automatic samplechanger The integrated motorizedrobot system allows measurement of up to three samples at the same time. The sample carriers are arranged on a robust sample carrier tube which rotates during sample change. For large sample sizes, the system can be equipped with a carrier plate for single sample operation. A highly sensitive MCT(Mercury Cadmium Telluride) Ir detector is generally used in the system. This detector covers the temperature range from -125 to 1100°C. For improved sensitivity at high temperatures, a InSb (Indium Antimonide) detector is additionally available. Both detectors can be changed by the operator within minutes. Detectors

TM integratesstate-of-the-art technology in a robust, easy-to-operate table-top measurement instrument. The laser pulse is guided by a mirror to the sample carrier within the furnace. The down-view IR- detector is directed to the rear surface of a sample. Short distances between light source, sample(s) and detector yield an excellent signal-to-noise ratio and permit easy operation and sample change. The wide range of different sample holders, detector types, and furnaces, along with the vacuum-tight design, allow easy adjustment of the system to nearly all possible applications. controlled liquid nitrogensupply and allows measure- ments between -125 and 500°C. The forced-air cooled high temperature furnace allows measurements between room temperature and 1100°C. The furnace is moved with a motorized hoist.
