LP840 Longpass IR Filter
- ModelLP
- SpecificationCustomizable
- MaterialOptical glass
Description
The LP840 longpass filter is designed to transmit infrared light beyond 840 nm while blocking visible and near-IR light below. Within the passband the transmission is typically above 90%, while the blocking band drops rapidly below 0.1%. Its stable, reliable performance suits infrared imaging, spectroscopy and biomedical imaging. Clean the surface regularly with proper optical tools; avoid chemical solvents and abrasive materials.
