These lights are energy-efficient, durable, and have a long lifespan. They are widely used in security cameras, barcode scanners, and medical equipment. - Thermal Infrared Sources: These sources emit infrared light at longer wavelengths, typically between 7.5 and 14 micrometers. They are used in thermal imaging cameras for applications such as building inspections, search and rescue operations, and wildlife observation. - Laser Diodes: Laser diodes are highly focused sources of infrared light. They are used in barcode readers, medical diagnostics, and precision measurements. - Infrared Filaments: These are resistive infrared sources that use a filament to produce infrared light. They are commonly used in industrial applications such as heat treatment and infrared heating.

Manufacturing Process

The manufacturing process of infrared light sources involves several critical steps: - Material Selection: The choice of materials is crucial for the performance and longevity of the infrared light source. Materials such as gallium arsenide (GaAs), indium gallium arsenide (InGaAs), and silicon carbide (SiC) are commonly used due to their excellent thermal and electrical properties. - Design and Engineering: The design phase involves creating a blueprint for the infrared light source, taking into account factors such as the desired wavelength, intensity, and power consumption. Advanced design software is used to simulate and optimize the performance of the device. - Wafer Fabrication: The wafer, which is the base material for the infrared light source, is produced through a process called epitaxy. This involves depositing thin layers of semiconductor materials onto a silicon wafer. - Dicing and Mounting: The wafer is then diced into individual chips, which are mounted onto substrates. This process ensures that the chips are securely attached and can be easily integrated into various applications. - Testing and Quality Control: Each infrared light source is rigorously tested to ensure it meets the required specifications. This includes testing for intensity, wavelength, and stability.
