We manufacture infrared filters for detecting various gases, such as H2O, CH4, CO2, CO, NO, SO2, SF6 and etc.
The wavelength is up to 16µm. These filters are widely used in environmental, medical. security, thermography and avionic industries.
Applications
Environmental Monitoring
Security Systems
Thermography Systems
Avionics
Benefits
Ultra-Narrow Band
High Transmission
Sharp Slope
High Contrast
