Customizable Si Infrared Window

The introduction of the Si Infrared window

A Si infrared window is an optical component. It is often used to transmit infrared radiation while protecting internal components of a system from dust, moisture, and environmental contaminants.

The infrared window is typically placed between the internal optics and the external environment in infrared systems.

 The Si infrared window is an optical component made from high-purity single crystal silicon. 

It transmits infrared light in the 1.2 to 7 μm range. With its excellent thermal conductivity and mechanical strength, people often use it in IR optical systems.

Chenyu Silicon Infrared Window are suitable for various infrared situations, especially in the 1.65 – 5 micron range.

Silicon is highly suitable for use in infrared precision instruments, providing better protection for components from environmental contamination.

Key Advantages of Silicon IR Windows

• Excellent infrared transmittance

The Si infrared window has excellent infrared light transmission performance In the wavelength range of 1.2 to 7 micrometers.

• High refractive index, clear imaging

The refractive index is approximately 3.4, which can effectively focus infrared light and enhance the resolution and clarity of the imaging system.

• High thermal conductivity, resistant to high temperatures

Silicon has high thermal conductivity, allowing for rapid heat dissipation in various environments.

• High cost-effectiveness

Compared to other infrared materials, the raw material cost of silicon is lower, making it suitable for large-scale procurement and integrated applications.

 

Appliaction of the Si infrared window

• Infrared thermal imaging instrument

People often use silicon infrared windows in industrial, security and medical infrared thermal imaging equipment.

And the window can isolate the internal sensors from the external environment while ensuring high light transmittance in the mid-infrared band.

• Medical infrared diagnostic systems

For medical devices such as infrared body temperature detectors and skin thermal imaging equipment, using silicon windows can enhance the accuracy of signal acquisition and the response speed of the system.

• Infrared Spectroscopy Analyzer (FTIR)

Infrared spectroscopy analyzers used for analyzing gas or liquid samples are often equipped with silicon window plates.

Because they cover the mid-infrared range required for analysis.

• Unmanned Aerial Vehicles & Security Thermal Imaging System

The silicon window is highly suitable for installation on unmanned aerial vehicles, serving as both a protective layer and for transmitting infrared signals.
