ON-SITE TRACTION DEVICE FOR EQUIPPING AN ANALYTICAL MICROSCOPY APPARATUS

摘要

The invention concerns an on-site traction device (1) for applying to a sample (2), a uniaxial biasing field, designed to be coupled to an analytical microscopy apparatus, thereby enabling the behavior of the sample, in particular the evolution of molecular characteristics during deformation, to be observed, the microspectrometry/traction device assembly thus allowing simultaneous acquisition the data (spectral image), the recording of the associated optical image, and the real-time measurement of the stress-strain curve, the device comprising at least: translational guide means (5) oriented along the direction of the biasing field, two opposite jaws (3), each borne, directly or indirectly, by a mobile arm (4, 41, 42) along the direction of the translational guide means (5), gear motor means (6), coupled and co-operating with drive means (7), to transform a rotational movement into two translational movements in opposite direction, for moving each of said jaws (3).
