AFM-拉曼和针尖增强拉曼散射(TERS)

AFM-Raman, nano-Raman and TERS home

One powerful tool for all your needs

Tip-Enhanced Raman (TERS): chemical imaging at the nanoscale

TERS brings you the best of both worlds: the chemical specificity of Raman spectroscopy with imaging at spatial resolution typically down to 10nm. This technique can be demonstrated on various samples ranging from 1D and 2D nanomaterials to DNA.

AFM-Raman and nano-Raman (TERS)

Unique features:


infrared AFM diode

Infrared AFM diode at 1300 nm: no optical interferences with the spectroscopy detection, for all SPM modes including all AFM modes.

Any typical laser can be used, from NUV to NIR, especially access to the red region for AFM required for TERS with gold probes.


Optical access

Optical access with high aperture objective lens (0.7NA) from both top and side: brings unequalled throughput and spatial resolution and optimized illumination conditions for TERS.


easy tip exchange

Simple tip exchange; fully automated alignment and tuning: no knobs to adjust to align the AFM laser.


High resonance-frequency scanner

High resonance-frequency scanner for high speed imaging and low sensitivity to acoustic vibrations. No need for active vibration isolation to obtain the true molecular resolution.


laser alignment visualization

Visual confirmation of alignment on all channels.


objective scanner

Short path-length and closed-loop objective scanner laser alignment: brings higher throughput and outstanding long term stability, critical for TERS imaging.

将您的所有需求集成到一个强大的系统中

HORIBA拉曼技术非常容易与扫描探针显微镜(SPM)耦联。我们所提供的完美解决方案使用直接光路耦合,对其进行优化以实现高通量。该平台可以把原子力显微镜(AFM)、近场光学技术(SNOM, NSOM)、扫描隧道显微镜(STM)和共焦光学光谱仪(拉曼和荧光成像)耦合到一台多功能的仪器中,以实现针尖增强拉曼散射(TERS)或共点测量。

HORIBA和几乎所有的知名制造商合作,包括AIST-NT、安捷伦、Asylum Research、布鲁克(原来的Veeco)、JPK、Nanonics和Park。

  • 针尖增强拉曼光谱(TERS)的光学、机械和软件都是经过优化设计的,同时有HORIBA在拉曼光谱几十年的经验做技术支持,您可以自信地使用这一技术。

一个工具多种可能:AFM-拉曼有助于您提高效率

快速找到纳米对象

Ultra-fast Raman mapping

由于纳米材料具有特殊的化学属性,拉曼峰信号较强,因此在光学显微镜下不可见的纳米材料可以通过超快速拉曼成像进行搜索和定位。在找到样品后,我们可以对感兴趣的位置进行形貌、机械、电学和热能分析。

交叉验证您的数据!

拉曼光谱可以证实材料的某些特性,例如前面研究的石墨烯,AFM形貌的对比度较差而难以确定层厚,拉曼则可以从另外一个角度去获得相同的信息,此外拉曼还提供更多有关结构和缺陷的信息,此信息只有具备原子分辨率的AFM才能提供。

获得感兴趣纳米结构的化学信息

在表征纳米结构时,有时仅获得物理性质是不够的。高分辨的拉曼共焦成像可提供详细的化学成分信息,这是其他SPM传感器无法实现的。
