Operate the FTIR 835 within 15-28°C and below 65% humidity to achieve specified performance. The spectrometer must be powered by a 12 VDC supply delivering at least 30W.
- Environmental Conditions: Maintain ambient temperature between 15-28°C and relative humidity under 65% during operation.
- Power Requirement: Connect the instrument to a stable 12 VDC power source with a minimum capacity of 30W.
How does the pendulum roof mirror optical system in the Atomfair FTIR 835 improve alignment reliability compared to traditional corner cube interferometers?
The Atomfair FTIR 835 uses a pendulum roof mirror interferometer that inherently maintains optical alignment without the need for dynamic calibration, which is typically required in corner cube designs. This innovation solves the optical alignment problems of traditional interferometers, providing long-term stability and reducing maintenance frequency. The design is described as avoiding traditional corner cube optical design and dynamic calibration requirements.
What environmental conditions must be maintained to operate the Atomfair FTIR 835 reliably in field or laboratory settings?
The Atomfair FTIR 835 is specified for operation within an ambient temperature range of 15–28°C and relative humidity below 65%. Exceeding these limits can affect optical alignment and promote condensation on sensitive components. The instrument includes a built-in drying oven to manage internal moisture, but the surrounding environment must still stay within these parameters for accurate performance.
Which sample handling methods are supported by the Atomfair FTIR 835 and how do the ATR reflection options affect analysis?
The spectrometer supports ATR (with 1 or 3 reflections), transmission, and reflection sampling methods. The ATR option provides convenient surface analysis of solids and liquids without extensive sample preparation; the choice between 1 and 3 reflections influences the path length and hence sensitivity for different sample types. The instrument comes with a standard multi-coated KBr beam splitter and an optional ZnSe beam splitter for different wavelength ranges, allowing adaptation to specific sample chemistries.
The Atomfair FTIR 835 Portable FTIR Spectrometer combines a compact pendulum roof mirror interferometer with a VCSEL laser frequency reference and 24-bit data acquisition, enabling rapid, drift-resistant analysis across 7000-400 cm⁻¹. Its multi-coated KBr beam splitter and ATR/transmission/reflection sampling options support versatile lab and field use, though operation is constrained to 15-28°C and below 65% humidity.
Positive
- Compact pendulum interferometer: The pendulum roof mirror optical system eliminates traditional corner cube dynamic alignment, reducing optical misalignment and enabling a compact 49×39×20 cm, 12 kg design suitable for field deployment.
- VCSEL laser frequency reference: The VCSEL laser provides a stable frequency reference, enhancing wavenumber accuracy and reproducibility across the 7000-400 cm⁻¹ range, critical for quantitative analysis.
Trade-offs
- Narrow operating temperature range: The instrument requires 15-28°C ambient temperature, limiting use in unconditioned outdoor environments without additional climate control.
- Humidity sensitivity: Operation is restricted to below 65% relative humidity; the built-in drying oven mitigates moisture but does not eliminate the need for humidity management in tropical or coastal settings.
