Product Details
OEM Optical Glass UV/Infrared Filter for Camera & Sensor
1. Material & Construction
Optical Substrates:
UV Filters: UV-grade fused silica (180–400nm transmission)
IR Filters: Colored glass (Schott RG-type) or coated BK7 (700–1200nm range)
Coatings: Hardened dielectric layers for bandpass/blocking (OD >6 rejection)
Custom Formats: Round, rectangular, or complex shapes (3–200mm diameter)
2. Key Properties
Precision Spectral Control:
UV Pass/Block: >95% transmission @ target band ±5nm tolerance
IR Cut: Sharp transition slopes (e.g., 650nm cut-on @ ±10nm)
Environmental Durability:
Thermal shock resistance: ΔT >150°C
Humidity resistance: 95% RH @ 85°C
Optical Integrity:
Surface flatness: λ/2 @ 633nm
Scratch resistance: 80-50 scratch-dig standard
3. Core Functions
Spectral Purity: Blocks unwanted UV/IR to enhance image accuracy
Sensor Protection: Shields CMOS/CCD from IR/UV degradation
Signal Optimization: Increases SNR in machine vision by eliminating ambient IR/UV noise
Color Fidelity: Prevents IR contamination in RGB imaging
4. Applications
Imaging Systems:
Security cameras (IR-cut for day/night switching)
Medical endoscopes (UV-blocking for tissue imaging)
Industrial Sensors:
LiDAR receivers (850nm bandpass filters)
Spectroscopy (custom bandpass for gas detection)
Automotive:
In-cabin monitoring sensors (IR-pass for eye tracking)
Autonomous vehicle LiDAR (905nm filters)
