The800–1100nm Reflective Neutral Density Filteris designed for
near-infrared optical systems requiring controlled light attenuation across a broad NIR wavelength range.
With a nominal50% transmittance, the filter reduces optical
intensity while maintaining stable spectral performance from800nm to 1100nm.
Manufactured from high-quality optical glass and combined with
precision reflective optical coating technology, this filter is
designed to provide consistent attenuation, low absorption and
reduced heat buildup compared with absorption-based attenuation approaches.
It is suitable forNIR laser systems, optical sensing,
machine vision, imaging equipment and scientific or industrial instruments.
The filter provides approximately50% optical transmittance,
allowing controlled reduction of light intensity while maintaining the required NIR spectral range.
This makes it suitable for optical systems requiring predictable attenuation.
The filter is designed for applications operating across the 800–1100nm near-infrared region.
This broad spectral range makes it suitable for various NIR optical systems.
Instead of relying primarily on absorption to reduce optical intensity,
the reflective coating redirects part of the unwanted optical energy.
This design can help reduce absorption-related heat buildup in suitable high-power optical systems.
A precision multilayer coating provides controlled attenuation
and stable optical performance across the specified wavelength range.
The optical glass substrate provides good durability,
optical uniformity and reliable performance for precision optical applications.
Provides consistent attenuation across the specified NIR wavelength range.
The reflective design helps minimize optical absorption
compared with attenuation approaches that rely heavily on absorbing materials.
By reflecting part of the optical energy rather than absorbing it,
the filter can help reduce heat buildup in appropriate applications.
The optical performance is designed to remain stable under changing operating conditions.
Precision optical processing provides a high-quality surface for dependable optical integration.
