OPT Cobra Series Liquid Fixed Focal Length Lense

OPT Cobra Series – Liquid Fixed Focal Length Lenses (Industrial Lenses)

The OPT Cobra Series Liquid Fixed Focal Length Lenses are innovative fixed focal length lenses with an integrated liquid lens, specifically designed for industrial machine vision and automated inspection systems. By using a liquid lens, this series enables dynamic autofocus with an extremely fast response time of under approximately 4 ms, allowing the focus to be adjusted almost instantly. This makes them ideal for applications with varying working distances or fast-moving objects.

Despite the dynamic focus adjustment, these lenses deliver high optical resolution of up to approximately 145 lp/mm. They are compatible with camera sensors up to around 2/3″ and pixel sizes of about 3.45 µm, ensuring sharp and highly detailed images. The liquid-lens-based focusing system offers excellent repeatability (± 0.1 dpt) and can be rotated 360° via a digital I/O interface, simplifying integration into compact or space-constrained system designs.

Typical applications include automated inspection systems with variable measurement distances, robot-guided processes, and tasks involving frequently changing object positions, where fast and precise focusing is critical.
