Product Overview
This high-performance M12 mount fixed focal lens (PN: JSD28491) is expertly engineered for 1/2.5-inch sensors, delivering superior image fidelity and geometric accuracy for advanced imaging applications. With a 2.9mm effective focal length and F2.8 aperture, it provides a wide 100° field of view, making it ideal for high-precision machine vision, scanning, and surveillance tasks. Featuring exceptional 10MP resolution and an ultra-low distortion design (<-1.5%), this lens ensures sharp, true-to-life images across the entire frame, even in demanding optical environments.
Key Features & Benefits
10MP High Resolution: Designed to support high-density sensors, delivering crisp, ultra-high-definition imaging with excellent edge-to-edge sharpness for detailed analysis and recognition tasks.
Ultra-Low Distortion (<-1.5%): Advanced optical correction significantly minimizes barrel distortion to less than 1.5%, maintaining straight-line accuracy and realistic spatial representation essential for measurement and mapping.
Perfect Sensor Match: Precision-optics optimized specifically for 1/2.5" sensors, featuring an image circle that eliminates vignetting and maximizes the sensor's active area.
Wide 100° FOV: Offers a broad 100° field of view, providing substantial scene coverage while maintaining a natural perspective, suitable for both indoor monitoring and outdoor observation.
Optimized F2.8 Aperture: The F2.8 aperture balances light intake with a deeply focused field, ensuring consistent clarity and depth of field for objects at varying distances.
Robust & Precise Build: Features a standard M12 thread and a Total Track Length (TTL) of 24mm, offering a durable and stable optical assembly suitable for integration into industrial and commercial devices.
Versatile Integration: The 2.9mm focal length combined with high resolution makes this lens highly adaptable for devices requiring both wide angles and high pixel density.
