IR Wide Bandpass Filter High Transmission 2.65μm to 5.50μm Applications:
- Infrared Gas Analysis: Many industrial greenhouse gases, such as CO₂, CH₄, NOₓ, and SO₂, have significant absorption characteristics in the 2.65-5.50μm band. This filter can detect and identify gases in infrared gas analyzers and non-dispersive infrared sensors.
- Infrared Imaging: In infrared imaging systems such as industrial furnace temperature monitoring and fire detection, this filter can avoid the absorption peaks of water vapor and carbon dioxide in the atmosphere for infrared imaging.
- Medical Diagnosis: In non-invasive medical testing and tissue composition analysis, this filter can selectively absorb wavelengths of human tissue and protein for infrared spectral imaging and diagnosis.
