470nm Bandpass Filter | 30nm FWHM | Deep OD6 Blocking
Engineered for high-precision signal isolation, this blue bandpass filter is optimized for the 470nm wavelength. It delivers exceptionally high transmission—greater than 90 percent—within the target passband (460-480nm) while providing superior, deep-band blocking outside this critical range. This ensures maximum signal capture while eliminating unwanted noise.

Typical Applications
The excellent signal-to-noise ratio, achieved through deep blocking (average Optical Density greater than 6), makes this component ideal for demanding instrumentation applications.
Key areas include high-sensitivity fluorescence detection, microscopy optics, and specific spectroscopy systems. The 470nm CWL is essential for isolating signals from specific fluorophores or LEDs.
It is also frequently specified for quantitative PCR detection systems and other medical diagnostic instruments where precise wavelength isolation and high signal purity are critical for accurate results.
