The BP780-34nm-1.1mm bandpass filter is engineered for high-efficiency detection in the near-infrared region, combining a wide 34nm full width at half maximum (FWHM) centered at 780nm with a compact 1.1mm substrate. Offering transmission greater than 90% across the robust 770-790nm window, this filter delivers significant throughput for IRDye 800CW, Cy7, and other deep NIR fluorophores, making it ideal for demanding deep-tissue, in vivo, or multiplexed imaging.

Key Performance Features
This NIR filter achieves a remarkable balance of signal strength and selectivity. The broad 34nm passband captures full emission spectra of IRDye 800, Cy7, and other NIR markers, perfect for high-throughput screening or low-signal applications. Peak throughput above 90% allows photon-limited or rapid dynamic scenarios—multiplexed imaging, in vivo biodistribution, and deep-tissue microscopy—where speed and sensitivity drive performance.
The deep blocking from 350-1100nm ensures clean fluorescence detection, suppressing both visible and far-infrared crosstalk. Optimized at 780nm, this filter exploits the NIR transparency window for exceptional tissue penetration, minimal autofluorescence background, and reliable quantitative imaging.
Applications
- Multiplexed in vivo imaging: Maximize Cy7 and IRDye 800CW emission separation in small animal and organ-level systems. - Rapid/high-throughput NIR screening assays: Clinical, pharmaceutical, and point-of-care platforms seeking strong signal and low noise. - Deep tissue microscopy: Confocal, widefield, and IVIS systems capturing weak NIR signals in thick samples or living organisms. - Automated filter wheels: The 1.1mm thickness fits dense filter assemblies with high alignment repeatability and robustness.
