LTH770 Narrow Bandpass Filter - 770nm ±2nm, FWHM 10nm for Sensitive Bio-Detection Systems

LTH770 Precision Narrow Bandpass Filter: Engineered for Critical Bio-Detection

Unlock Signal Clarity in Biological Sensing
The LTH770 is a high-performance narrow bandpass optical filter designed for demanding bio-detection applications. Centered at 770nm with ultra-tight FWHM 10nm tolerance, it delivers exceptional out-of-band rejection (OD >6) and peak transmission >90%, ensuring maximum signal-to-noise ratio for sensitive biomedical instrumentation.

Key Features:
✅ Targeted Wavelength: 770nm ±2nm (CWL) – Optimized for hemoglobin/oxygen sensing, fluorescence biomarkers, and NIR spectroscopy.
✅ Ultra-selective Bandwidth: FWHM 10nm ±1nm – Isolate critical biological signals while rejecting ambient noise.
✅ High Optical Performance: >90% peak transmission, OD6 blocking (200-730nm & 810-1100nm).
✅ Robust Durability: Hard-coated on BK7/UVFS substrate – Resists humidity, scratches, and chemical exposure (IEC 61340-5-1 compliant).
✅ Angle-Stable Design: Minimal shift (<1nm) at 0-15° incidence – Consistent performance in compact devices.

Applications in Life Sciences:

• Lab-on-a-Chip (LOC) Diagnostics

• Flow Cytometry & Cell Sorting

• NIR Fluorescence Microscopy

• Portable Blood Oximetry & Biosensors

• DNA Sequencers & PCR Systems

Technical Superiority Meets Reliability
Fabricated using ion-assisted deposition (IAD) technology, the LTH770 maintains >95% transmission stability after 1,000 hrs of 85°C/85% RH stress testing. Each filter includes a certified spectral report traceable to NIST standards.
