仪器简介：
典型应用： 

Assessment of two dimensional morphologies
Microcontact printing
Investigation of two dimentional surface pattern

全自动扫描。 

表面等离子共振（SPR） 
测量时间在亚毫秒量级，可以灵敏地测量亚单分子层的厚度，光学常数，质量分布，是用来研究快速反应动力学的理想工具，它已成为生物传感领域的一种标准技术。 
SPR实验简单，功能强大。 
软件通过四种模块来实现功能： 
1 角-角反射率扫描 
2 动力学模块的快速角跟踪 
3 反射率跟踪 
4 数据处理 
我们可以为用户提供SPR传感片。 

波导模法 
适合各向异性的介质薄膜的测量，它更适合用来描述厚度超过500 nm的薄膜，凭借它的高精度，其他技术还没办法与之竞争。对特定偏振态的测量要选择相应的折射率，再进行数据处理，这是与椭偏法最主要的不同，而且所有的折射率分量都要同时考虑。 

布鲁斯特角显微镜法 
清晰呈现分子方位，倾斜度，旋转度，典型的测量区域是20-200μm,反射率系数为10-6时就可以清晰成像。它比荧光显微镜方法更有优势，因为不需要作荧光标记，这样就会避免一些不必要的影响。 

接触角法 
可以获得关于表面成分的重要信息。在固相衬底上的液滴形状由表面张力和地球重力决定，通过分析三相线可以获得接触角。 
软件可以自动区分液滴或平面，这与很多商用的程序不同，这就避免了繁杂的输入，使测量快速，精确，友好。

技术参数：
将多种表面测量方法组合在一起.包括:

椭偏仪
表面等离子体共振光谱分析仪
波导模分析仪
反射计分析仪
布鲁斯特角显微镜分析仪
表面等离子体共振显微成像光谱分析仪
成像椭偏仪
接触角分析仪

主要特点：
功能强大。多才多艺

椭偏法：
可以获得：

精度在0.1nm的薄层厚度
衬底的光学常数
分子取向
表面质量分布
表面结构形态
快速获取数据功能使观测诸如腐蚀、吸附等过程成为可能，测量不具有破坏性，适合多种样品的测量，即使液－液界面也可以实现。
椭偏仪的应用十分广泛：
Assessment of scaling laws
Ion distribution
Photochemisty
Adsorption isotherms
Corrosion
Characterization of thin films
Glass transition in confined geometries
Determination of optical constants
Swelling experiment

配用不同的测量模块,可以进行

多区域测量
椭偏反射扫描
动力学模块（可记录温度，表面张力，湿度，PH值）

所有的重要参数都可以在线控制，软件非常人性化，因为它是由在自身科研领域就用到椭偏仪的科学家设计的。

成像椭偏法
横向解析度为2μm, 纵向解析度为0.1nm,可以清晰呈现单分子层结构。

  • 薄膜样品中厚度检测方案
    Ellipsometry is a very sensitive measurement technique that uses polarized light to characterize thin films, surfaces,and material microstructure. Usually the polarization of light changes upon reflection. These changes are measured by an ellipsometer and interpreted on the basis of model calculations.

  • 薄膜中薄膜厚度检测方案(椭偏仪)
    In the 1980s, there was great enthusiasm about molecular assemblies based on Langmuir–Blodgett (LB) films. Visions were proposed for the next millennium such as “Molecular electronics in which organic molecules perform an active function in the processing of information and in transmission and storage” (1–3). These proposals raised many expectations. Being now at the beginning of a new millennium, this review will aim to critically assess the accomplishments and perspectives.

    The orientation, structure, and energetics of the vapor/acetone-water interface are studied with sum frequency generation vibrational spectroscopy (SFG-VS). We used the polarization null angle (PNA) method in SFGVS to accurately determine the interfacial acetone molecule orientation, and we found that the acetone molecule has its CdO group pointing into bulk phase, one CH3 group pointing up from the bulk, and the other CH3 group pointing into the bulk phase. This well-ordered interface layer induces an antiparallel structure in the second layer through dimer formation from either dipolar or hydrogen bond interactions. With a double-layer adsorption model (DAM) and Langmuir isotherm, the adsorption free energies for the first and second layer are determined as ¢G°ads,1 ) - 1.9 ( 0.2 kcal /mol and ¢G°ads,2 ) - 0.9 ( 0.2 kcal /mol, respectively. Since ¢G°ads,1 is much larger than the thermal energy kT ) 0.59 kcal /mol, and ¢G°ads,2 is close to kT, the second layer has to be less ordered. Without either strong dipolar or hydrogen bonding interactions between the second and the third layer, the third layer should be randomly thermalized as in the bulk liquid. Therefore, the thickness of the interface is not more than two layers thick. These results are consistent with previous MD simulations for the vapor/pure acetone interface, and undoubtedly provide direct microscopic structural evidences and new insight for the understanding of liquid and liquid mixture interfaces. The experimental techniques and quantitative analysis methodology used for detailed measurement of the liquid mixture interfaces in this report can also be applied to liquid interfaces, as well as other molecular interfaces in general.

  • 油水空气中关于油/水, 空气/水界面的过渡态研究检测方案(椭偏仪)
    Insoluble monolayers at the air-water interface are exposed to a gas phase containing organic hydrocarbons. The hydrocarbons are partly incorporated within the monolayer which leads to changes in orientational order and the formation of new phases of different morphology. The transition state resembles features of the air-water and oil-water interface and the control of the hydrocarbon partial pressure allows continous tuning between both interfaces. The phospholipid D,L-R-dipalmitoylphosphatidylethanolamine,DPPE, and an esterdiol hexadecanoic acid, 2,3-dihydroxypropyl ester, ESD-16, are used as amphiphiles, and pentane, n-hexane, cyclohexane, 2,2-dimethylbutane, n-heptane, n-decane, and n-dodecane are used as hydrocarbons. Both amphiphiles differ in their headgroup size. In DPPE the aliphatic tail determines the packing within the monolayer, but in the case of ESD-16 it is the headgroups.The structural changes are monitiored by surface pressure-area (ð,A) isotherms and imaging ellipsometry.The influence of the chemical nature of the hydrocarbon and the effect of the partial pressure of the hydrocarbon on the monolayer structure are assessed.

  • 铁电液晶波导中相位匹配二次谐波的产生检测方案(椭偏仪)
    True phase-matched second-harmonic generation in a waveguide of crosslinkable ferroelectric liquid crystals is demonstrated. These materials allow the formation of macroscopically polar structures whose order can be frozen by photopolymerization. Homeotropic alignment was chosen which offers decisive advantages compared to other geometries. All parameters contributing to the conversion efficiency are maximized by deliberately controlling the supramolecular arrangement.The system has the potential to achieve practical level of performances as a frequency doubler for low power laser-diodes.
