460 nm Narrow Bandpass Optical Filter

The 460 nm narrow bandpass optical filter is a highperformance bandpass filter specifically designed for wavelengths around 460 nm. It efficiently transmits the target band of 453-467 nm while providing deep blocking of offband light on both sides of the passband, effectively suppressing background light, stray light, and adjacent wavelength interference, thereby improving the signaltonoise ratio, wavelength selectivity, and detection accuracy of optical systems. The filter achieves an average transmittance greater than 90% over the 453-467 nm band, with an average blocking depth of OD5 or higher over the ranges of 360-435 nm and 486-800 nm, and provides blocking of OD3.5 or higher at 438.5 nm and 481 nm. Offered in a standard 25 mm round form with a clear aperture of ≥21 mm, the filter supports an incident angle of 0°± 5°and a cone halfangle of 7°, allowing easy integration into microscopes, spectrometers, fluorescence detection instruments, and other precision optical systems. With its high inband transmittance, excellent outofband blocking, and good longterm light stability, the 460 nm narrow bandpass optical filter is suitable for fluorescence imaging, biomedical detection, spectral analysis, machine vision, bluelight detection, and research applications.
