原位纤维拉伸拉曼测试台 FiberStage | 香港量子科技有限公司

产品简介Overview

FiberStage 是一台小型精密拉伸装置，可与显微拉曼光谱系统联用，在纤维等小尺寸样品被拉伸的过程中，实时采集样品同一位置的光谱信号。FiberStage is a compact precision tensile stage that couples to a Raman microscope, acquiring spectra at the same spot while a small sample (e.g. a fiber) is being stretched.

材料被拉伸时，分子链是滑移还是取向？裂纹从哪里萌生？应力如何集中？过去这类问题常常"拉完再看"——实验结束后才去表征，变形过程中的关键瞬间已经错过。拉曼光谱对分子键振动高度敏感，材料受力时特征峰会发生移动（"应力–频移"效应）；通过实时追踪峰位移动，即可反推局部应力与应变状态。When a material is stretched, do molecular chains slip or orient? Where does a crack initiate? How does stress concentrate? Previously such questions were studied only after the test. Raman is highly sensitive to molecular-bond vibration: under stress, characteristic peaks shift (the "stress–shift" effect), allowing local stress and strain to be inferred in real time.

设备自重约 1 公斤，外形 160 × 110 × 34 mm，体积小巧，适合放置在显微镜载物台或光谱仪样品台上，作为显微光谱系统的原位附件扩展仪器能力。At only ~1 kg and 160 × 110 × 34 mm, it sits on a microscope stage or spectrometer sample stage as a compact in-situ accessory.

使用方法Operation

安装Installation — 先装 USB 驱动，再装拉伸台控制软件（按 Setup 提示完成）install USB driver then the control software (Setup wizard)
归零Zeroing — 开机后将驱动端推到与另一端间隙最小，点击 Set Origin，位置与拉力归零drive to minimum gap, then Set Origin to zero position and force
装样与实验Sample & run — 固定纤维样品，设定拉伸距离后 Start 自动拉伸；也可手动点动逐步加载mount fiber, set distance and Start (auto), or jog manually
数据处理Data — 实时绘制"拉力–位移"曲线，数据以 .cuv 纯文本保存 / 打开 / 删除live force–distance curve; data saved / opened / deleted as plain .cuv
系统设置Setup — 含拉力传感器校准（用已知拉力校准器）、电机速度/加速度、最大距离与最大力限定load-cell calibration, motor speed/acceleration, max distance/force limits

注意：Note: 供电为直流 12 V，切勿使用高于 12 V 电源以免烧毁控制器；驱动电机为步进减速电机、力量较大，手勿置于运动模块趋近端；软件每次启动会自动将拉力传感器归零，请确保启动时无负载。Power: DC 12 V only — do not use a higher voltage. The geared stepper motor is powerful; keep hands away from the moving stage. The software auto-zeroes the load cell on start — ensure no load is applied.
