JSD2639

Product Overview

This high-definition M12 mount fixed focal lens (Model: JSD2639) is precision-engineered for 1/2.8-inch sensors, delivering superior 4K clarity with advanced optical correction. With a short 2.1mm focal length and F2.4 aperture, it offers a wide 116° field of view while maintaining exceptional geometric accuracy. Distinguished by its low distortion design (<-4%), this lens eliminates the significant "fish-bowl" curvature typically found in wide-angle optics, making it ideal for high-precision machine vision, facial recognition, and professional surveillance where straight lines and true-to-life representation are critical.

Key Features & Benefits

True 8MP Resolution:Supports high-definition 4K UHD imaging, capturing intricate details with sharpness from center to edge, perfect for high-resolution sensors.

Low Distortion Design (<-4%):Features an advanced optical structure that drastically reduces barrel distortion to less than -4%, ensuring straight lines remain straight and images look natural.

Wide 116° Field of View:Provides a broad viewing angle for comprehensive scene coverage without the heavy visual deformation associated with standard fisheye lenses.

Optimized for 1/2.8" Sensors:Specifically designed with a 1/2.8" image circle to perfectly match popular CMOS sensors, ensuring full sensor coverage without vignetting.

Precision Aperture:The F2.4 aperture balances light intake with depth of field, ensuring sharp focus across the scene.

Compact & Durable:Built with a standard M12 thread and a TTL of 24.5mm, this lens offers a robust solution for integration into compact cameras, drones, and industrial devices.
