• Low-light imaging and astronomical applications

Technical Excellence

The BP460-75's extra-broad 75nm bandwidth represents the optimal balance between spectral selectivity and light collection efficiency. This wide passband captures significantly more photons than narrow-band alternatives, providing superior signal-to-noise ratios in light-limited applications while still maintaining excellent spectral discrimination with OD2 (100:1) blocking performance.

This broad bandwidth design is particularly advantageous when working with LED sources, which typically exhibit broader emission spectra than laser sources. The filter efficiently captures the full spectral output of blue LEDs (typically 440-480nm), maximizing system efficiency and reducing exposure times in imaging applications.

Manufactured using advanced multi-layer thin-film coating technology, the BP460-75 delivers consistent performance across the entire aperture with minimal transmission variation. The hard-coated surfaces ensure durability in demanding laboratory and industrial environments, maintaining optical quality through years of continuous use.

The 75nm bandwidth also provides excellent tolerance for LED wavelength variations due to temperature changes or manufacturing differences, ensuring consistent performance across different light sources and operating conditions.

Whether you're conducting fluorescence imaging with weak signals, developing LED-based optical systems, performing color analysis, or working in low-light conditions, the BP460-75 provides the perfect combination of broad spectral coverage and maximum light throughput.
