The OPTOStokes LP800 series is a high-performance 800nm longpass filter designed to effectively isolate the near-infrared spectrum by providing a sharp transition from deep blocking to high transparency. This longpass filter is engineered for precision systems requiring a clean optical cutoff filter to eliminate visible light interference and enhance signal-to-noise ratios in NIR applications.

Applications
Due to its high transmission and reliable cutoff characteristics, the LP800 is an essential component for:
- NIR Imaging & Machine Vision: Improving contrast in automated inspection by filtering out ambient visible light.
- Laser Detection: Protecting sensors from stray light while passing 808nm or 940nm signals.
- Biometric Systems: Enhancing infrared facial or iris recognition accuracy.
- Medical Diagnostics: Used in NIR imaging and fluorescence analysis where deep red suppression is required.
