About This Filter
Our 30% neutral density filter provides precise, uniform light attenuation across 350-1100nm, reducing intensity by 70% while maintaining spectral neutrality. At just 0.21mm thick, it’s ideal for space-constrained systems needing consistent 30%±3% transmission.
Key Advantages
- Uniform 30%±3% transmission across 350-1100nm for consistent light control
- Ultra-thin 0.21mm design fits tight spaces in compact optical systems
- Spectrally neutral—preserves color balance in imaging and measurement
- 60/40 surface quality minimizes scattering, ensuring clean signal transmission
Applications
- Laser Systems: Safely reduces 350-1100nm laser intensity to protect detectors without altering beam characteristics
- Compact Imaging: Controls exposure in small-format cameras and endoscopes where space is limited
- Spectroscopy: Adjusts light levels to match detector ranges, improving accuracy in material analysis
