FTIR Spectrometer ST-530

• High sensitivity & stability
• Intelligent real-time instrument status monitoring
• Multiple communication options
• Flexible & convenient testing
• Powerful software workstation

Features

1. High Sensitivity Optical System

   Cube-corner Michelson interferometer combined with patented fixed-mirror alignment technology (Utility Model ZL 2013 2 0099730.2: Fixed-mirror alignment assembly) ensures long-term stability without complex dynamic alignment circuits. Gold-coated reflective mirrors maximize light throughput and guarantee detection sensitivity.
2. High-Stability Modular Partition Design

   Compact, modular structure mounted on a cast-aluminum base delivers excellent mechanical robustness, partitioned heat dissipation, strong deformation resistance, and low sensitivity to vibration and temperature changes, greatly improving mechanical and long-term operational stability.
3. Intelligent Multi-Sealed Moisture-Proof Design

   Multi-sealed interferometer, large-capacity desiccant cartridge with visible window and easy-replace structure, plus real-time internal temperature & humidity monitoring, effectively protect the optical system from high temperature, high humidity, and chemical corrosion.
4. Innovated Integrated Electronic System

   High-sensitivity integrated DLATGS detector pre-amplifier, dynamic gain amplification, high-precision 24-bit A/D conversion, real-time control & data processing, digital filtering, and network communication technologies ensure high-quality real-time data acquisition and high-speed transmission.
5. Excellent Anti-Electromagnetic Interference Capability

   Electronic system designed to meet CE certification and EMC requirements. Electromagnetic radiation is minimized in both design and technology, in line with the green instrument concept.
6. High-Intensity IR Source Assembly

   High-intensity, long-life IR source with peak energy in the fingerprint region. Reflective sphere design provides uniform and stable IR radiation. External isolated source module and large heat-dissipation chamber ensure superior thermal stability and consistent optical interference.
7. Universal Sample Compartment

   Wide sample compartment with reserved accessory mounting holes on the base plate, compatible with diffuse/specular reflection, ATR, liquid cell, gas cell, IR microscope, and other accessories.
