Your Technical Guide to Choose the Right Lens for EOIR Systems
Selecting the right EOIR lens is critical for achieving accurate detection, tracking, and imaging performance in defence and aerospace systems. Factors such as spectral range, focal length, sensor compatibility, field of view, and environmental conditions all play an important role in lens selection. Whether for airborne surveillance, thermal imaging, border security, or long-range observation, choosing the correct EOIR optics helps maximize image clarity, improve target identification, and ensure reliable performance in mission-critical applications.
EO/IR lens selection is fundamentally driven by the required DRI performance. The DRI calculation is primarily influenced by the camera’s resolution, pixel size, lens focal length, and the target’s size.
Lens selection is also guided by the required angle of view. Wider fields of view are commonly needed in defence and drone applications, and these are achieved through shorter focal lengths and appropriate larger pixel size
Defence systems operate across the Visible, NIR, SWIR, MWIR, and LWIR bands, ensuring lens compatibility with the specific spectral range is critical. Across these spectrums, both fixed focal length and variable (zoom) lenses are in demand
Fixed focal lenses are always limited the maximum focal length options available within 100mm. Defence applications would prefer Zoom lenses varying focal lengths and zoom levels to achieve long distance imaging
Lens selection also depends on size and weight constraints based on the platform—airborne, maritime, or ground-based systems. Airborne applications, prioritize compact and lightweight lenses to minimize payload weight and improve overall efficiency
In case of Zoom lenses, motorized lens control for Iris, Zoom and Focus is important. Auto focus lens options are available for specific models, where the lens can automatically adjust its focus position to keep the image sharp
