About This Filter
Our 850nm bandpass filter is engineered for precise near-infrared (NIR) wavelength isolation. It delivers >90% transmission at 850nm (±2nm) while blocking 350-1100nm light to<0.1%—critical for applications needing clean, focused NIR signal.
Key Advantages
- High transmittance (>90%) at 850nm for strong signal throughput
- Broad blocking (350-1100nm @ T<0.1%) eliminates background interference
- Stable center wavelength (850±2nm) ensures consistent performance
- Durable coating withstands NIR exposure and industrial handling
Applications
- NIR Imaging: Enhances 850nm signal in night vision and thermal systems, sharpening imagery
- Laser Systems: Isolates 850nm laser beams from ambient light, boosting system efficiency
- Machine Vision: Improves contrast in NIR inspection, aiding defect detection in electronics/automotive
