High sensitivity optical system: cube-corner Michelson interferometer combined with patented fixing mirror alignment technology to ensure long term stability, without the need of dynamic alignment. Reflecting mirrors are coated with gold to provide the maximum light throughput and ensure the detection sensitivity.

High stability modular partition design: compact structure modular design with layout on cast aluminum base and overall balance of mechanical robustness and partition heat dissipation, offering higher ability of deformation resistance and less sensitive to vibrations and thermal variations, greatly improves the mechanical stability and long term working stability of the instrument.

Intelligent multi-sealed moisture-proof design: multiple sealed interferometer, large-capacity desiccant cartridge with visible window and easy replacement structure, real-time monitoring of temperature and humidity inside the interferometer, getting rid of influences of high temperature, high humidity and chemical corrosions to the optical system in many ways.

Innovated integration electronic system: high sensitivity integrated DLATGS detector pre-amplifier technology, dynamic gain amplification technology, high precision 24-bit A/D conversion technology, real-time control and data processing technology, digital filter and network communication technology, ensuring high quality real-time data collection and high-speed transmission.

Good anti-electromagnetic interference capability: The electronic system is designed to meet CE certification and electromagnetic compatibility requirements, minimizing electromagnetic radiation in design and technology in line with the ‘environmentally friendly’ designing concept.

High intensity IR source assembly: High intensity, long lifetime IR source module, with the highest energy distributed in fingerprint region, adopts a reflex sphere design to obtain even and stable IR radiation. External isolated IR source module and large space heat dissipation chamber design provide higher thermal stability and stable optical interference.

The sampling compartment, reserving accessory mounting holes on the base plate, is wide enough for various accessories such as Defused/Specular Reflection, ATR, Liquid cell, Gas cell, and IR microscope etc.
