High Resolution Lenses
Overview
Theia’s high-resolution lenses (up to 12MP, 300 lp/mm) are Near IR corrected for multi-spectral and Day/Night applications and are available in both motorized and non-motorized versions. Built for industrial and machine vision environments where pre‏cision, reliability, and real-time decision-making are essen‏tial, these lenses deliver the clarity and pixel density needed for robotics, factory automation, and intelligent trans‏portation systems.
Their advanced resolution supports detailed imaging for object detection, defect inspection, autonomous navigation, and iden‏tification at longer distances or across wider fields of view. Fast apertures enhance low-light performance, while IR correc‏tion keeps visible and infrared light on the same focus plane for consistent 24/7 operation—ideal for high-speed tolling and ANPR/LPR applications.
Compact by design, these lenses integrate easily into space-constrained systems such as drones and autonomous mobile robots. Motorized options and P-iris control enable remote operation and fine-tuned image control. With support for multi‏ple sensor sizes and focal lengths, Theia’s high-resolution lenses deliver exceptional performance in a compact, cost-‏effective package.
