D100mm / D120mm Neutral Density Optical Filter
TheD100mm / D120mm Neutral Density (ND) Optical Filteris designed to precisely control
and reduce light intensity while maintaining excellent spectral neutrality across the visible spectrum.
With large100mm and 120mm diameteroptions and multiple transmission levels,
this optical attenuation filter is suitable for systems requiring controlled light reduction over a large optical aperture.
The filter uses high-quality optical glass and precision optical coating technology
to provide uniform attenuation, stable transmission and low color shift.
Large optical systems often require attenuation filters with a larger active aperture.
This product is available in:
Both sizes are suitable for large-aperture optical assemblies, testing equipment, imaging systems and other applications requiring large-diameter attenuation.
Different optical systems require different attenuation levels.
The available transmission options include multiple levels from very low transmission to high transmission.
Available D100mm products include:
Standard D100mm thickness:2mm
Available D120mm products include:
Standard D120mm thickness:2mm
This wide range of transmission levels allows users to select
an appropriate attenuation level according to their optical system.
The ND filter is designed to provide uniform light attenuation while maintaining good spectral neutrality.
Key performance advantages include:
The filter is manufactured usinghigh-quality optical glass.
The optical glass substrate provides a stable foundation for the attenuation structure
and supports the requirements of precision imaging, measurement and optical testing systems.
