The Computar CMP-M5018-MP, also referred to as the M5018-MP2, is a 50mm fixed focal length C-mount lens designed for industrial machine vision, factory automation, image processing, and quality control systems. Built for 2/3" sensors, it delivers sharp, high-contrast images with low distortion for precision inspection and measurement applications.
Model: Computar CMP-M5018-MP / M5018-MP2; focal length: 50mm; aperture range: F1.8-F16C; iris type: manual iris; sensor format: 2/3"; image circle: up to 11mm; mount: C-mount; optical class: 1 to 1.5 megapixel machine vision.
• 50mm fixed focal length supports tight, high-magnification inspection views.
• Low-distortion optical design helps preserve measurement accuracy.
• Edge-to-edge clarity maintains strong contrast and light intensity across the image.
• Manual iris range from F1.8 to F16C provides exposure control for controlled lighting setups.
• Locking set screws secure focus and iris settings in vibration-prone industrial environments.
The CMP-M5018-MP is engineered to capture the full resolution of compatible 1 to 1.5-megapixel cameras. Its 13.1° diagonal field of view and 50mm focal length make it suitable for focused inspection tasks, component measurement, and robotic guidance where detail and repeatability matter.
Use with compatible 2/3" C-mount cameras. Set the working distance and illumination, adjust focus and iris for the target inspection area, then tighten the locking set screws to maintain stable optical settings during operation.
