Spring Series In-Situ Holders(Optics)

Product Features

Using MEMS microfabrication technology to construct a liquid atmosphere nanolaboratory in an in-situ sample holder, light is loaded onto the sample stage as an external field condition through the fiber optic embedded in the sample stage. The sample is stimulated by the light source introduced by the MEMS chip and fiber optic, and various different modes such as EDS, EELS, SAED, HRTEM, STEM are used to measure optical properties simultaneously, achieving real-time measurement from the nano or even atomic level Dynamically monitor key information such as microstructure evolution, reaction kinetics, phase transitions, elemental valence states, chemical changes, microstresses, and atomic level structure and composition evolution at the surface/interface of samples in a liquid atmosphere environment, as a result of changes in the light field.

    Highest resolution in the industry ·1.Using the original MEMS processing technology, the thickness of silicon nitride film in the chip window area can reach 10nm.
    ·2.The chip packaging adopts a double insurance method of bonding inner seal and epoxy resin outer seal, making the thinnest interlayer between the chips only about 100-200 nm. The ultra-thin interlayer greatly reduces interference with the electron beam, allowing for clear observation of the atomic arrangement of the sample, and achieving atomic level resolution in the liquid phase environment.
    ·3.Specially designed chip window shape can avoid the thickening of liquid layer caused by the bulging of silicon nitride film, which may affect the resolution.
    High security ·1.The common liquid sample holders of other brands on the market, due to the limitations of their own liquid pool chip design scheme, can only drive a large flow of liquid through the sample stage and the peripheral area of the chip through the huge pressure generated by the liquid pump,which poses a safety hazard of a large amount of liquid leakage. The liquid mainly enters the nano pores in the middle of the chip through diffusion effect,and there is no real flow rate control in the chip observation window.
    ·2.Adopting patented nanofluidic technology, fluid differential control is achieved through a piezoelectric micro control system to achieve nano upgraded micro fluid transportation. The redundant liquid volume in the in-situ nanofluidic system and sample holder is only slightly increased, effectively ensuring the safety of the electron microscope.
    ·3.Adopt the polymer membrane surface contact sealing technology,compared with the O-ring sealing,the sealing contact area is incre ased,effectively reduce the risk of leakage.
    ·4.Using ultra-high temperature coating technology, the silicon nitride film in the window area of the chip has advantages such as high temperature resistance,low stress,pressure resistance, corrosion resistance,and radiation resistance.
    Unique multi-field coupling technology ·It can realize multi-field coupling of light,electricity,heat and fluid in liquid phase environment.
    Excellent optical performance ·1.Adopt integrated laser light source,integrated UV-Vision-Infrared different bands and output specific wavelength laser.The output optical signal has high power (the maximum strength is not less than 150mW/cm2),the light intensity can be adjusted rapidly and continuously,and the response time can reach millisecond level.
    ·2.Adopt special structure design, optical loss is very low,energy is stable and uniform.
    Intelligent software and automation equipment ·1.Man-machine separation,software remote adjustment laser band and intensity,program automatic control of tilt Angle.
    ·2.The whole process is equipped with precision automation equipment to assist manual operation and improve experimental e fficiency.
    Advantages of R&D team ·1.Team leaders participated in the development and completion of in situ liquid phase TEM at the early stage of development.
    ·2.Our team independently designed in-situ chips,mastered the core technology of chips,and owned multiple chip patents.
    ·3.Our team has more than 20 people engaged in in situ liquid phase TEM research, which can provide technical support for in-situ experiments in multiple research directions.
