1.90 - 6.00 µm Bandpass Filters
Encompassing the mid-infrared (MIR) spectral region, this band is highly sensitive to thermal radiation from high-temperature objects, capable of penetrating specific atmospheric windows and non-metallic materials, while containing characteristic absorption spectra from molecular vibrational-rotational energy transitions.
- Application 1: Infrared Thermal Imaging SystemsFilters out visible and near-infrared interference to isolate thermal radiation signals from high-temperature targets like industrial machinery or power cables, enhancing fault detection accuracy by focusing on critical mid-infrared emission signatures.
- Application 2: Gas Spectral Analysis InstrumentsSelectively blocks out-of-band radiation to enable precise capture of unique absorption peaks for greenhouse gases such as CO₂ and CH₄ within their mid-infrared spectral fingerprint regions, facilitating quantitative analysis of atmospheric compositions or industrial exhaust gases.
- Application 3: Remote Sensing EquipmentBy isolating specific mid-infrared wavelengths, it penetrates complex meteorological conditions like clouds and fog to acquire spectral data on vegetation water content, soil thermal properties, or geological mineral compositions, supporting agricultural yield estimation and environmental monitoring applications.
