Fourier transform infrared microscope

FTmicro10 is a research grade product independently developed and innovatively designed by Yingsa OpticsFourier transform infrared microscopeThis infrared microscope integrates high-definition visible light observation and high-performance infrared spectroscopy measurement, and measures micro area samples with the highest infrared spatial resolution.

The FTmicro10 infrared microscope has high resolution in visible and infrared light, as well as multifunctionality in mid infrared and near-infrared testing. It has a wide spectral range and high sensitivity, and can perform various measurement modes such as microscopic transmission, reflection, ATR measurement, temperature change measurement, microscopic emission measurement, etc. It can be easily switched with just a touch of a button, reducing the operational intensity of experimenters and solving the measurement difficulties of various micro materials in scientific research and production quality control.

The observation system of FTmicro10 infrared microscope combines the characteristics of "high resolution" and "multifunctionality". It can be switched directly through panel buttons, which is intuitive and easy to operate, providing innovative design for infrared measurement of microscopic samples. The "Observation" system is equipped with two LED light sources and a 12 megapixel high-resolution camera, which can freely switch between visible light transmission and reflection, and display visible images clearly on the computer screen; The "measurement" system can switch between infrared transmission, reflection, and ATR measurement modes directly on the panel. The following is a schematic diagram of a high-precision ATR objective lens and its optical path. What you see is what you get!

FTmicro10 standard configuration includes XYZ manual sample stage, 20x focusing lens, 20x reflective objective lens, high-precision blade aperture, liquid nitrogen cooled MCT detector, covering application fields such as materials science, biological products, chemical environmental protection, forensic science, and art protection. The system can be upgraded to a fully automatic high-precision sample stage, equipped with a micro ATR lens, optional room temperature DTGS detector, electrically cooled indium gallium arsenide detector extended to the near-infrared spectral range, etc., to meet the research needs of users for different application scenarios.

Product Principle

The interference light of the infrared spectrometer is output to the infrared microscope through a switching mirror, and the interference light is focused on the sample through the infrared objective lens. Users can measure micro areas with a spatial resolution of less than 10 microns by adjusting the aperture size. The transmitted or reflected light of the sample enters the infrared detector to obtain the infrared interference pattern of the sample, thereby obtaining the chemical composition and physical information of the sample. An infrared microscope consists of two parts: a visible light path and an infrared light path. The visible light path includes a visible light source and a visible light camera; The infrared light route consists of an infrared objective lens, a focusing lens, and an infrared detector. Two part coaxial optical path design, "what you see is what you get", observes and measures micro area samples through a high-precision sample stage.
