Core Product Advantages
Compact and Flexible: Slightly larger than A4 paper in overall size, it occupies minimal space, making it suitable for various laboratories or narrow spaces and saving valuable venue resources.
Stable and Reliable Optical System: The optical bench adopts an integrated aluminum structure design, with core components positioned once and no need for subsequent adjustments, greatly improving mechanical stability and long-term reliability. The one-piece gold-plated corner mirror offers excellent matching consistency, an enlarged reflection surface ensuring higher light flux and reflectivity. With high vertical precision on each surface and a bond-free design that is not affected by ambient temperature, the instrument’s stability is further guaranteed.
High-Performance Electronic System: Equipped with 24-bit A/D conversion technology and matched with an imported detector, it ensures true and reliable data, real-time collection, and high-speed transmission, guaranteeing detection efficiency and result accuracy.
Multi-Layer Moisture-Proof Protection: Combines moisture-proof solutions such as a sealed interferometer design, visual desiccant replacement reminder, and moisture-resistant window panes, effectively resisting the impact of humid environments on the instrument and extending its service life.
Rich Accessories and Strong Expandability: Attachment replacement and experimental installation are simple and convenient. It supports a variety of extended testing accessories, including a dedicated single-reflection ATR accessory (with push-card positioning installation), gas cells, liquid cells, and solid pellet inserts, meeting the needs of different detection scenarios.
Compliance Assurance: The supporting software features a “three-level management authority” function, complying with relevant testing specification requirements. 3Q certification installation service is provided to ensure compliant use of the instrument.
Applications
Widely used in fields such as pharmaceuticals, materials, chemicals, environmental protection, quality inspection, and universities, covering scenarios including laboratory testing, teaching and scientific research, and vocational training. It is an ideal choice for both professional testing institutions and educational institutions seeking efficient and reliable analytical equipment.

This instrument requires a dry operating environment to prevent moisture damage to the hygroscopic KBr beam splitter and optical components. The power supply must be a stable AC220V/50Hz source, and the instrument should be used with a computer running Windows XP, 7, or 10 via USB 2.0.
- Moisture Sensitivity: The KBr beam splitter with germanium coating is hygroscopic and requires a dry atmosphere; the instrument's multi-layer moisture-proof protection includes a sealed interferometer, desiccant replacement reminder, and moisture-resistant window panes.
- Electrical Supply: The instrument operates on AC220V/50Hz and must be connected to a grounded outlet with stable voltage to prevent damage to the electronic system.
- Software and Data Interface: Data transmission is via USB 2.0, and the instrument is compatible only with Windows XP, Windows 7, and Windows 10 operating systems.
- Installation and Alignment: The optical bench uses an integrated aluminum structure with pre-aligned core components; factory or certified 3Q installation is recommended to ensure long-term stability.
What is the effective spectral range of the Atomfair-FTIR-639 and how does the 1.0 cm⁻¹ resolution perform within that range?
The Atomfair-FTIR-639 operates in the near-infrared region covering 7800±350 cm⁻¹, approximately 7450 to 8150 cm⁻¹. It offers a spectral resolution of 1.0 cm⁻¹, which is typical for compact FTIR spectrometers and suitable for resolving fine spectral features in near-IR analysis of organic compounds.
What moisture protection features does the Atomfair-FTIR-639 include to ensure reliable operation in humid laboratories?
The instrument incorporates a sealed interferometer design, a visual desiccant replacement reminder, and moisture-resistant window panes. These multilayer moisture-proof measures protect the KBr beam splitter with germanium coating and maintain optical stability in environments up to typical lab humidity conditions.
What are the power, size, and interface requirements for installing the Atomfair-FTIR-639?
The spectrometer requires AC220V/50Hz power and has a compact footprint of 355mm × 265mm × 160mm, weighing 9.6 kg. It uses a USB 2.0 interface for data transmission and is compatible with Windows XP, 7, and 10 operating systems.
The Atomfair-FTIR-639 is a compact, portable FTIR spectrometer with a 1.0 cm⁻¹ resolution and a sealed, moisture-proof interferometer, designed for routine laboratory and educational use. Its integrated aluminum optical bench and gold-plated corner mirror provide mechanical stability, while the 24-bit A/D conversion and imported pyroelectric detector ensure reliable data acquisition. The instrument's performance is specified under controlled conditions, and its operation requires a stable AC220V/50Hz power supply and a dry environment, with compatibility limited to Windows XP/7/10.
Positive
- Compact and stable optical design: The integrated aluminum optical bench with a one-piece gold-plated corner mirror requires no post-installation alignment, ensuring long-term mechanical stability and consistent optical performance in space-constrained laboratories.
- High sensitivity and moisture protection: With a signal-to-noise ratio better than 30000:1 (P-P, 4 cm⁻¹, 1-min scan) and a sealed interferometer with desiccant indicator and moisture-resistant windows, the instrument delivers reliable data in humid environments while extending component lifespan.
Trade-offs
- Requires dry, climate-controlled lab: Despite multi-layer moisture-proofing, the KBr beam splitter and optical path remain sensitive to humidity; the instrument must be operated in a low-humidity environment and the desiccant must be monitored and replaced regularly to prevent spectral degradation.
- Limited OS and power compatibility: The spectrometer only supports Windows XP/7/10 and requires a 220V/50Hz supply, which may necessitate a transformer or dedicated power infrastructure in regions with different voltage/frequency standards, and restricts use with modern operating systems.
