Precision Machine Vision Unleashed: LTH970 Narrow Band IR Filter (850nm)
10nm Bandwidth | 90% Transmission | Industrial-Grade IR Clarity
In machine vision systems where ambient light, glare, or low-contrast scenes sabotage accuracy, spectral precision is non-negotiable. Manufactures solves this with the LTH970 Narrow Band IR Filter—engineered for 850nm illumination to deliver unmatched contrast, noise immunity, and reliability in demanding machine vision applications.
Engineered for Optical Perfection
Ultra-selective 850nm Passband: Precisely centered at 850nm – the gold standard for covert NIR machine vision.
Razor-Sharp 10nm Bandwidth: Aggressively blocks ambient visible/IR noise (e.g., sunlight, LEDs).
90% Peak Transmission: Maximizes signal strength for faster exposure times.
OD6+ Deep Blocking: Blocks >99.9999% of out-of-band light (400–800nm & 900–1100nm).
Built for Industrial Punishment
Thermal-Stable Hard Coatings: Withstands -40°C to +120°C operating temps (zero delamination).
Abrasion-Resistant Glass: MIL-C-675C compliant – survives conveyor dust, cleaning, and impacts.
Low Angle Shift (<0.5%): Consistent performance across wide-angle lenses.
Transform Your Vision System
Key Applications:
Defect Detection: Spot micro-cracks in glass/electronics under intense IR illumination.
Material Sorting: Classify plastics, textiles, or recyclables via NIR reflectance.
Automated Inspection: Read codes on dark/reflective surfaces (tires, PCBs, metal).
Agricultural Sorting: Identify defects in produce using NIR absorption signatures.
Security & Surveillance: Enable 24/7 covert imaging with 850nm IR illuminators.
Robotic Guidance: Achieve sub-millimeter precision in low-light assembly lines.
Seamless Integration
Standard Sizes: 12.5mm, 25mm, 50mm rounds (C-mount, CS-mount compatible).
Custom Formats: Squares, rectangles, or custom thickness (0.5–5mm substrates).
Coating Options: AR-coated backside for multi-sensor arrays.
