仪器简介：
纤维拉伸台可安装在SEM或光显微镜的样品台上。使用此纤维拉伸台，可对力度极低的拉伸实验进行现场观察，精确拉伸力控制 (低至 1x10 N)，拉伸速度为0.1 -- 20 μm/s，可精确测量直径低至2.5μm,长几毫米的纤维，在超过10，000x来对样品进行动态或静态观察。
拉伸力通过装载弹簧金属线的频率变化来测量，位移则由示差变换器(LVDT)测量。
The outer dimensions of the Fiber Tensile Module are 80 x 100 x 22mm³, it is mounted to
the SEM or light microscope specimen stage "like a large specimen". It allows in-situ
observation of tensile testing experiments at extremely low forces, yet very high load
resolution (down to 1x10 N). The tensile speed range is 0,1 to 20 μm/s. These features,
coupled with maximumstiffness of this substage, allowvery accurate measurements on
fibers of down to 2.5 μmdiameter, and several millimeters length. The specimens can be
observed statically or dynamically at magnifications well beyond 10'000 x in daily routine
work.
The load is measured by the principle of frequency variations on a spring-loaded metal
wire. The displacement is taken byadifferentaltransformer (LVDT).
The enlarged view shows the specimen holder, which is a pair of ceramic tubes, ground
down to half their diameter (red tips). One side is attached to a parallel sled, driven by a
combination of DC-tacho-motor/angular encoder for precise recognition of the
displacement. A fine tungstenwire touches the specimenfromunderneath at 90 degrees.
This wire allows heatingupthe specimenlocally.
