About This Filter
Our 70% neutral density filter provides precise light attenuation across 350-1100nm, reducing intensity by 30% while maintaining spectral neutrality. With 70%±3% transmission, it preserves color balance—critical for applications needing controlled light reduction without distortion.
Key Advantages
- Uniform 70%±3% transmission across 350-1100nm for consistent light control
- Spectrally neutral design preserves color integrity in imaging and measurement
- 1.1mm thickness balances durability with system integration flexibility
- 60/40 surface quality minimizes scattering, ensuring clean beam profiles
Applications
- Imaging Systems: Reduces harsh light in high-brightness scenes (e.g., outdoor photography) while retaining natural color
- Laser Testing: Moderates 350-1100nm laser intensity for component testing without altering beam characteristics
- Spectroscopy: Fine-tunes light levels to match detector sensitivity, improving signal-to-noise ratios in analysis
