The 485nm Narrow Bandpass Filter is a precision optical filter
designed to transmit light around the 485nm center wavelength
while effectively suppressing unwanted out-of-band light.
With a10nm FWHM bandwidthandOD5 blocking performance,
this optical filter provides high spectral selectivity for optical
systems requiring accurate wavelength discrimination and strong background-light suppression.
The filter uses a high-qualityoptical glass substrate with
multilayer optical coating, providing stable optical performance and reliable long-term operation.
An optionalmetal mounting frameis available for convenient installation
and mechanical protection, making the filter suitable for integration
into optical instruments and imaging systems.

The10nm FWHMbandwidth provides selective
transmission around the 485nm target wavelength.
Compared with broad optical filters, the narrow passband helps
optical systems isolate the required spectral region and reduce unwanted background light.
This makes the filter suitable for applications where wavelength accuracy,
spectral selectivity and signal-to-noise performance are important.
The filter providesOD5 blocking, helping suppress
unwanted wavelengths outside the transmission band.
Strong out-of-band attenuation can help reduce back
ground interference and improve the quality of optical signals in detection and imaging systems.
The blocking range can be customized according to the requirements of the optical system.
The filter is manufactured using an optical glass
substrate with a precision multilayer optical coating.
The coating structure is designed to provide:
Different substrate and coating configurations can be discussed
according to the application and wavelength requirements.
For customers requiring easier system integration,
the 485nm optical filter can be supplied with a metal mounting frame.
The mounted configuration can provide:
Round, square and other custom configurations are available.
