Infrared optical materials exhibit substantial changes in their refractive indices with temperature variations, resulting in unstable focal lengths in IR thermal imaging cameras. This instability is undesirable, especially in critical applications. To counteract this issue, athermalization techniques are employed to eliminate defocus across extended temperature ranges.
Athermalization Techniques:
1.Passive Optical Athermalization:
- Utilizes different lens materials with complementary Coefficients of Thermal Expansion (CTEs) to counteract thermal focus shift.
- Advantage: Simplified structure without spatial displacement of lenses, making it compact and lightweight.
2.Passive Mechanical Athermalization:
- Involves mechanical components that adjust the lens position as temperature changes.
3.Active Electromechanical Athermalization:
- Uses sensors and actuators to actively adjust the lens position in response to temperature variations.
