400–1100nm Reflective Neutral Density Attenuation Filter (6% Transmission)
The 400–1100nm Reflective Neutral Density (ND) Attenuation
Filter is designed to provide controlled and stable light reduction
across the visible to near-infrared wavelength range.
With a fixed transmission of 6%, it ensures accurate attenuation
while maintaining excellent spectral consistency.
This filter features a reflective neutral density design,
which effectively reduces heat absorption compared to absorptive filters.
A high-precision multilayer thin-film coating is applied to a premium
optical-grade glass substrate, delivering uniform attenuation,
low optical loss, and long-term environmental stability.
To meet different system requirements, the filter is available
in multiple standard sizes and supports custom dimensions,
thicknesses, and coating specifications.
It is well suited for laser attenuation,
optical measurement, imaging systems,
laboratory instruments, and industrial optical applications.
