Products Description
BP840nm Narrow Bandpass Filter | FWHM 20nm for Fluorescent Imaging
The OPTOStokes BP840nm narrow bandpass filter is meticulously engineered for high-sensitivity near-infrared (NIR) applications. Providing exceptional transmission coupled with ultra-deep out-of-band blocking, this interference filter effectively isolates weak optical signals from background noise, delivering world-class precision for advanced optical setups.
Technical Specifications
| Parameter | Specification |
|---|---|
| Center Wavelength (CWL) | 840 plus or minus 2 nm |
| Full Width at Half Maximum (FWHM) | 20 plus or minus 2 nm |
| Peak Transmission Range | 835 to 845 nm at T greater than 90 percent |
| Ultraviolet to Visible Blocking | 350 to 820 nm at OD greater than 5 |
| Near-Infrared Close Blocking | 860 to 900 nm at OD greater than 5 |

Key Applications
Tailored specifically for small animal in vivo imaging systems, the BP840nm filter delivers the extreme contrast required to detect faint deep-tissue fluorescence. By providing an optical density greater than 5 (OD 5) blocking across crucial excitation wavelengths, it eliminates excitation light leakage and suppresses background autofluorescence. This ensures precise signal separation in live-animal molecular imaging and fluorescence tomographic systems.
Customization & Manufacturing Services
OPTOStokes supports your research and development phase with an extensive in-stock selection of premium narrow bandpass filters for rapid prototyping.
