Technical Excellence

The 716nm wavelength occupies a strategic position at the transition between far-red and near-infrared spectral regions, making it invaluable for applications requiring detection beyond the visible spectrum. Our BP716-25 filter's narrow 25nm bandwidth provides excellent spectral resolution, enabling precise isolation of this wavelength while rejecting adjacent spectral regions with minimal interference.

With OD6 (1,000,000:1) blocking performance, this filter delivers exceptional out-of-band rejection critical for sensitive fluorescence applications and biomedical imaging. The superior blocking ensures that weak NIR fluorescence signals can be detected without interference from excitation light or emissions from other sources, making it ideal for demanding research applications in life sciences and medical diagnostics.

The 716nm wavelength is particularly significant for biomedical imaging applications, as it provides enhanced tissue penetration compared to visible light while maintaining compatibility with silicon-based detectors. This wavelength range is increasingly used in medical diagnostics, therapeutic monitoring, and in-vivo imaging applications where deep tissue penetration is essential.

Manufactured using state-of-the-art ion-beam sputtering technology, the BP716-25 delivers consistent performance across the entire aperture with minimal transmission variation. The hard-coated surfaces ensure durability in demanding laboratory and clinical environments, maintaining optical quality through years of continuous use in fluorescence microscopy and biomedical imaging systems.

The narrow 25nm bandwidth is particularly valuable for applications requiring precise spectral discrimination, such as multi-color fluorescence imaging where multiple NIR fluorophores with overlapping emission spectra must be clearly separated. This narrow bandwidth minimizes spectral crosstalk and enables more accurate quantitative measurements in biological imaging experiments.

The filter is also excellent for laser line filtering applications, providing clean spectral isolation for 716nm laser diodes commonly used in biomedical and industrial systems. The narrow bandwidth ensures that only the desired laser wavelength is transmitted, improving system performance and measurement accuracy.

Whether you're conducting NIR fluorescence imaging for biomedical research, performing laser line filtering for optical systems, building optical coherence tomography instruments for medical diagnostics, or developing multi-color flow cytometry systems, the BP716-25 provides the wavelength precision and optical quality that professional research and medical applications demand.
