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

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.
