Product Overview
This premium M12 mount fixed focal lens (PN: JSD65219) is expertly engineered for 1/2.5-inch sensors, delivering superior optical performance and exceptional low-light capabilities. With a 4mm focal length and a large F1.6 aperture, it provides a focused 78° field of view, making it ideal for biometric systems, video conferencing, and security monitoring where lighting conditions vary. Featuring 5MP resolution and a precision low-distortion design (<-1.0%), this lens ensures sharp, rectilinear images with excellent clarity and detail retention.
Key Features & Benefits
5MP High Resolution: Delivers clear, high-definition imaging with excellent detail, ensuring reliable performance for object detection, recognition, and general surveillance tasks.
Superior Low-Light Performance (F1.6): The impressive F1.6 large aperture allows significantly more light to reach the sensor compared to standard lenses, ensuring bright, low-noise images even in dim environments.
Low Distortion Design (<-1.0%): Optical optimization reduces barrel distortion to less than 1.0%, maintaining straight-line accuracy and true-to-life subject representation, essential for facial recognition and scanning.
Perfect Sensor Match: Designed specifically for 1/2.5" sensors, ensuring the image circle perfectly covers the active pixel area without vignetting or edge resolution loss.
Focused 78° FOV: Provides a standard, natural field of view that avoids the perspective distortion of ultra-wide lenses, perfect for focusing on specific subjects or areas (e.g., hallways, faces).
Compact & Robust Build: Features a standard M12 thread and a compact Total Track Length (TTL) of 20mm, allowing for seamless integration into compact camera housings and industrial devices.
Versatile Application: The combination of a large aperture and standard focal length makes this lens highly versatile for both indoor and outdoor applications requiring high sensitivity and clear subject focus.
