Detail Information

Custom Multi-Crystal IR Optical Substrate Window For Infrared Sensor

 
Felix Glass multi-material infrared optical window is customized for infrared thermal sensors, gas analyzers and FTIR spectrometers, supplying 7 mainstream infrared crystal substrates: Germanium (Ge), Zinc Selenide (ZnSe), Silicon (Si), Magnesium Fluoride (MgF₂), Calcium Fluoride (CaF₂), Lithium Fluoride (LiF), Barium Fluoride (BaF₂).
 
Each material covers different spectral bands from deep ultraviolet to long-wave infrared, meeting different infrared detection demands. Flat parallel window structure acts as protective substrate for infrared sensor chips, isolating dust, moisture and corrosive gas. Custom broadband AR anti-reflection coating and DLC hard coating can be deposited on both sides to raise infrared transmittance and boost scratch & moisture resistance. Square, round, rectangular special outlines and arbitrary thickness are fully OEM customizable.
 

Core Optical Specifications

 
- Optional Substrates: Ge, ZnSe, Silicon, MgF₂, CaF₂, LiF, BaF₂ single crystal
- Transmission Range
1. MgF₂/LiF: Deep UV to mid IR
2. CaF₂/BaF₂: UV to mid-long IR
3. Si/Ge: Mid & long-wave infrared
4. ZnSe: Visible to far infrared for CO₂ laser & thermal imaging
- Custom Coating: UV AR, IR AR, DLC anti-ablation composite coating
- Target Band Transmittance: ≥88%~95% after coating
- Surface Quality: Standard 60-40 scratch-dig, aerospace grade 20-10 optional
- Custom Parameter: Custom dimension, thickness, edge chamfer, cut-off wavelength coating
 

Core Product Advantages

 
1. Seven kinds of infrared crystal materials available, cover full UV-mid-far infrared spectrum for all infrared sensor scenarios
2. Flat parallel window design, perfect protective substrate for infrared sensor chip, stable under long-term detection work
3. Custom AR/DLC composite coating improves transmittance and anti-scratch, anti-moisture performance
4. Support square, round, special irregular outline customization, match compact infrared sensor module structure
5. Low internal impurity, low absorption, effectively reduce infrared signal loss and improve detection accuracy
6. Small lab sample & mass industrial batch order both acceptable, complete spectral test report provided
 

Typical Application Scenarios

 
- Non-contact infrared temperature sensor module protective window
- Industrial gas infrared absorption detection optical substrate
- Laboratory FTIR Fourier transform infrared spectrometer
- Vehicle, outdoor thermal imaging infrared camera window
- Medical infrared body temperature detection equipment
- Aerospace airborne multi-spectral infrared detection assemblies

 

OEM Manufacturing Capability

 
We provide full one-stop crystal processing including multi-crystal blank double-sided ultra-precision polishing, vacuum AR/DLC composite coating deposition, edge chamfer treatment, spectral transmittance testing, clean room packaging. Small trial sample and mass OEM supply are supported. Every infrared substrate window passes full spectral and surface quality inspection before delivery.
 

Standard FAQ

 
1. How to choose substrate material for infrared sensor?
Short-wave UV detection choose MgF₂/LiF; mid-infrared gas analysis choose CaF₂/BaF₂; long-wave thermal imaging choose Si/Ge/ZnSe.
2. Can I customize anti-reflection coating for specific infrared wavelength?
Yes, we customize AR coating matched to 2~14μm infrared band according to sensor working wavelength.
3. What shapes can this IR window be customized into?
Square, round, rectangle, special irregular outline, all thickness and size can be customized as drawings.
4. Is this optical window only for infrared sensor?
It also fits FTIR spectrometers, industrial laser equipment and high-temperature infrared monitoring optical systems.
5. Do you supply small quantity samples for sensor R&D testing?
We accept 1 piece small R&D sample order and provide full spectral transmittance test certificate.
