Introduction

The auto focus thermal camera module is a pivotal component in modern thermal imaging technology. By automating the focus adjustment, these modules enhance the accuracy and efficiency of thermal cameras, which are widely used in various industries for detection and monitoring purposes.

Principles of Thermal Imaging

Thermal imaging works by detecting infrared radiation emitted by objects. Infrared radiation is a form of electromagnetic radiation with wavelengths longer than visible light. The intensity of this radiation increases with temperature, allowing thermal cameras to visualize heat patterns.

Auto Focus Mechanism in Thermal Cameras

Auto focus in thermal cameras is achieved using motorized lenses that adjust based on feedback from the image sensor. The process involves:

1. Image Analysis: The camera continuously analyzes the image sharpness.
2. Feedback Loop: A control system processes sharpness data to adjust the focus mechanism.
3. Motor Adjustment: The lens position is altered using stepper motors to achieve optimal focus.

Technical Specifications

Typical parameters for an auto focus thermal camera module include:

• Focal Length: 19 mm to 75 mm
• Resolution: Up to 640 x 480 pixels
• Thermal Sensitivity: Less than 50 mK at f/1.0
• Frame Rate: 30 Hz to 60 Hz
