Infrared Imaging LP890 Longpass Filter
- ModelLP890
- SpecificationCustomizable
- MaterialCustomizable
Description
The LP890 longpass filter transmits near-infrared light above 890 nm and effectively removes visible and UV light. It is widely used in infrared imaging, IR inspection, night vision, biomedical research, infrared communication and IR laser systems. In thermal imaging and IR cameras it passes only long-wave IR for clear, accurate images; in laser ranging, scanning and cutting it removes unwanted wavelengths to keep the beam accurate and stable.
