The **OPTOStokes LP580 Longpass Filter** (P/N: 2200300016) is engineered for high-sensitivity optical systems requiring superior short-wave rejection. Designed with a precisely controlled 580nm cut-on, this longpass filter achieves maximum attenuation of unwanted visible and UV light (350-565nm) while maintaining exceptional throughput across the 575nm to 825nm passband. This filter is crucial for maximizing the signal-to-noise ratio in demanding analytical instruments.

Applications Requiring High Background Suppression
The **OD5 Deep Blocking** characteristic positions the LP580 as a core component in systems where high excitation light leakage cannot be tolerated.
- High-Sensitivity Fluorescence Detection: Ideal as an emission filter in fluorescence optics, specifically for Fluorophores emitting above 580nm (e.g., Rhodamine, Cy3), ensuring clean separation from blue/green excitation sources.
- Confocal Microscopy & Flow Cytometry: Provides the necessary noise reduction for low-signal biological assays and spectral measurements.
- Advanced Imaging Filter Systems: Used in industrial inspection and remote sensing where scattered short-wave ambient light must be eliminated for optimal data acquisition.
