LTH850 Precision 850nm Filter: Enhance Biometric Accuracy with IR Narrowband Technology

Product Description:

Unlock Precision in Biometric Security with the LTH850 Narrow Bandpass Filter

The LTH850 is an advanced infrared narrow bandpass filter engineered to deliver exceptional optical performance for cutting-edge biometric identification systems. Centered at 850nm with ultra-narrow bandwidth (FWHM), it selectively transmits critical near-infrared (NIR) light while aggressively blocking unwanted visible and IR noise. This enables higher signal-to-noise ratios, sharper image contrast, and unmatched reliability in sensitive biometric applications.

Key Features & Benefits:
✅ 850nm Center Wavelength (CWL): Optimized for IR-sensitive biometric sensors (vein recognition, facial authentication, iris scanning).
✅ Ultra-Narrow Bandwidth (<10nm FWHM): Minimizes ambient light interference for crystal-clear imaging.
✅ High Peak Transmission (>90%): Maximizes signal efficiency and reduces power requirements.
✅ Deep Out-of-Band Blocking (OD >5): Blocks UV, visible light, and stray IR for pure NIR signal capture.
✅ Hard-Coated Durability: Robust dielectric coatings ensure long-term stability in demanding environments.
✅ Low Angular Sensitivity: Consistent performance across varying incident angles (0-15°).

Ideal for Next-Gen Biometric Systems:
• Vein Pattern Recognition
• 3D Facial Authentication
• Iris Scanners
• Multi-Modal Security Devices
• Access Control & Payment Terminals
