Computar F3526-MPT 45 Megapixel 1.4" 35mm F2.6 (C Mount) Machine Vision Lens

The Computar F3526-MPT is a high-resolution 35mm fixed focal length lens engineered for precision-driven machine vision and industrial imaging applications. Designed to support up to 45 megapixels, this lens is optimized for large-format sensors up to 1.4”, delivering exceptional clarity, contrast, and edge-to-edge sharpness—making it ideal for advanced inspection, metrology, and automation systems.

Built to pair with modern high-density sensors such as the Sony IMX350 (2.74μm pixel size), the F3526MPT ensures accurate image reproduction with minimal aberration. Its low distortion optical design enables precise measurements and reliable image analysis, critical in applications where accuracy is non-negotiable. The F2.6 aperture balances light sensitivity and depth of field, supporting consistent performance across a range of lighting conditions.

With a compact, lightweight form factor and durable construction, this lens is well-suited for integration into space-constrained systems, robotics, and inline inspection setups. The manual iris control allows fine-tuning for exposure and depth of field, giving engineers flexibility in dynamic environments.
