Key Performance Features
This NIR filter enables efficient capture of Cy7, IRDye 800CW, and similar markers, ensuring robust fluorescence signal for deep tissue, in vivo, and automated imaging. The 23nm FWHM delivers an optimal balance between specificity and strong throughput—well-suited to biodistribution studies, low-light conditions, or high-throughput multi-color platforms.
The 2.0mm thickness provides excellent planarity and thermal stability for large system integration, maintaining reliable spectral properties even under varying environmental and illumination conditions. The coating ensures long-term durability and low background in demanding research or OEM settings.
Applications
- Near-infrared deep tissue and live animal imaging: Enhanced detection of Cy7 and IRDye 800, ideal for preclinical, surgical, or organ-level studies. - High-throughput NIR plate readers and automated assays: Increased signal collection for clinical diagnostics and pharmaceutical screens. - Multi-channel confocal/widefield/microscopy: Consistent spectral separation for high-parameter fluorescence detection. - OEM and system integrators: The 2.0mm filter is robust for custom assemblies and hybrid system installations.
