Product Overview
This high-performance M12 mount fixed focal lens (PN: JSD12938) is expertly engineered for 1/2.5-inch sensors, delivering exceptional clarity and superior geometric accuracy for advanced imaging applications. With a 3mm focal length and F2.5 aperture, it provides a distinct 92° field of view, offering a perfect balance between wide-area coverage and object detail. Featuring True 8MP resolution and an advanced optical design with distortion < -0.8%, this lens ensures professional-grade image sharpness and minimizes the "fisheye" effect, making it ideal for precision scanning, biometrics, and high-quality surveillance.
Key Features & Benefits
True 8MP Resolution: Delivers crisp, high-definition 4K UHD imaging with exceptional detail retention, ensuring clarity even for fine text or facial details.
Superior Low Distortion (<-0.8%): Features highly optimized optics with distortion less than -0.8%, maintaining excellent straight-line accuracy and true-to-life proportions—critical for machine vision and recognition algorithms.
Perfect Sensor Match: Engineered specifically for 1/2.5" sensors, featuring an optimized image circle that eliminates vignetting and fully utilizes the sensor's resolution capabilities.
Natural Wide 92° FOV: Provides a versatile 92-degree field of view that covers a broad area without the extreme perspective distortion common in ultra-wide lenses, reducing blind spots while keeping subjects looking natural.
Precision Optical Structure: With a TTL of 20.5mm, this lens incorporates a sophisticated glass structure to correct aberrations and ensure consistent performance.
Compact & Robust Build: Standard M12*P0.5 thread ensures seamless integration into standard board cameras, housings, and embedded devices.
Manual Focus Ready: The threaded mount allows for precise manual focal tuning during assembly to match specific object distances, optimizing sharpness for critical applications.
