The475nm Narrow Bandpass Optical Filteris a precision wavelength-selective filter
designed to transmit light around the475nm center wavelengthwhile reducing unwanted wavelengths outside the passband.
With a25nm FWHM bandwidth, this filter provides selective transmission around the target
wavelength and is suitable for optical systems requiring reliable spectral discrimination.
The filter is manufactured using anoptical-grade glass substrate with precision dielectric coating,
providing stable spectral performance, high transmission and good coating durability.
Round and square configurations are available, while custom dimensions,
thicknesses and wavelengths can be supplied for OEM optical applications.

The filter is designed around a475nm center wavelength, providing selective transmission of the required blue spectral region.
The25nm FWHMpassband allows the filter to transmit a controlled wavelength
range around the center wavelength while suppressing unwanted
spectral components outside the passband.
This makes the filter suitable for optical systems
where wavelength selection is required without using an extremely narrow spectral window.
The25nm FWHMspecification defines the approximate width of the
filter's transmission band at half of its maximum transmission.
This bandwidth provides a practical balance between wavelength selectivity
and optical signal throughput for many imaging, sensing and detection applications.
For applications requiring a different bandwidth, customized filter designs are available.
