Product Overview
This high-precision M12 mount fixed focal lens (PN: JSD85307) is expertly engineered for 1/2.5-inch sensors, delivering superior definition and optically perfect geometry for long-range and precision imaging applications. With an 8mm focal length and a bright F1.8 aperture, it provides a focused 50° field of view, making it ideal for license plate recognition (LPR), biometrics, and industrial measurement. Featuring 5MP resolution and a near-zero distortion design (<-1%), this lens ensures exceptional image sharpness and straight-line accuracy across diverse lighting conditions.
Key Features & Benefits
5MP High Definition Resolution: Optimized to resolve 5 megapixels, delivering crisp, detailed imaging necessary for identifying objects, reading text (OCR), and capturing fine details at a distance.
Bright F1.8 Aperture: The fast F1.8 aperture allows ample light to reach the sensor, providing excellent low-light performance and faster shutter speeds compared to standard F2.0 lenses.
Virtually Distortion-Free (<-1%): Advanced optical engineering reduces barrel distortion to less than 1%, eliminating the "fisheye" effect and ensuring straight lines remain straight—critical for accurate measurement and recognition.
Focused 50° FOV: Provides a narrower, magnified field of view (50°) compared to standard wide lenses, allowing for detailed monitoring of specific targets or narrow areas like traffic lanes and corridors.
Perfect Sensor Match: Engineered specifically for 1/2.5" sensors (and compatible with 1/2.7", 1/2.8"), featuring an image circle tailored to eliminate vignetting and maximize sensor capabilities.
Compact & Robust Build: Standard M12*P0.5 thread and a Total Track Length (TTL) of 24mm ensure seamless integration into bullet cameras, industrial housings, and board-level modules.
