About This Filter
Our 20% neutral density filter provides uniform light attenuation across 350-1100nm, reducing intensity by 80% while maintaining spectral neutrality. With precise 20%±3% transmission, it’s ideal for applications requiring consistent light reduction without color distortion.
Key Advantages
- Uniform attenuation (20%±3%) across 350-1100nm for consistent results
- Spectrally neutral—preserves color balance in imaging and measurement
- 60/40 surface quality minimizes scattering, maintaining beam integrity
- 1.1mm thickness with other options available from stock
Applications
- Laser Systems: Reduces 350-1100nm laser intensity to protect detectors and optics from overload
- Photography/Imaging: Controls exposure in high-brightness scenarios without altering color rendition
- Spectroscopy: Adjusts light intensity to match detector dynamic range, improving measurement accuracy
