The LP500-1.1mm longpass filter is engineered to provide precise spectral separation at the 500nm edge for high-clarity fluorescence, microscopy, and laser/LED systems. Transmission exceeds 90% from 510–1100nm, while blue-green light below 500nm is efficiently blocked (<1% T from 350–490nm). The 1.1mm thick substrate combines mechanical stability with a compact form factor for demanding OEM and research assemblies.

Key Performance Features
This longpass filter achieves excellent blue blocking and high transmission for green/yellow/red/NIR bands. The sharp 500nm edge allows efficient separation of excitation/emission in multi-dye or multi-laser setups, and reduces background in widefield, confocal, or laser-based platforms. Quality coatings deliver durable performance and low autofluorescence, even in high-power or automated systems.
Applications
- Blue-block filters for fluorescence: GFP, FITC, YFP, and multi-color detection in research and clinical instruments. - Laser/LED and multi-spectral imaging: Efficient NIR/Vis separation in industrial and analytical systems. - Flow cytometry and OEM integration: High-throughput detector modules, compact filter cubes, and automated optics. - Educational and instrument retrofitting: SNR improvement and spectral management for upgrade/maintenance needs.
