Product Overview
The JSD73291 is a compact M9 mount fixed focal lens expertly engineered for 1/4-inch image sensors, offering a versatile balance of wide coverage and optical precision. With a 2.4mm focal length and F2.8 aperture, it provides a broad 95° field of view, making it ideal for situational awareness and group capture without the heavy barrel distortion typical of fisheye lenses. Featuring 3MP resolution and a low distortion design (<-1.5%), this lens ensures sharp, natural-looking images, making it an excellent choice for biometrics, video conferencing, and compact smart home devices.
Key Features & Benefits
3MP High-Definition Clarity: Optimized to resolve 3MP resolution, delivering crisp and clear imaging suitable for HD video streaming, facial recognition, and detailed surveillance.
Wide 95° Field of View: Provides an expansive viewing angle that captures a wide area—perfect for monitoring rooms or capturing multiple subjects—while maintaining a natural perspective.
Low Distortion Design (<-1.5%): Advanced optical correction minimizes distortion to less than 1.5%, significantly reducing the "fish-bowl" effect and ensuring straight lines remain relatively straight for accurate scene representation.
Optimized for 1/4" Sensors: Precision-engineered with an image circle tailored for 1/4-inch sensors, ensuring full sensor utilization and consistent brightness from the center to the corners.
Compact M9 Form Factor: Built with a specialized M9 thread and a Total Track Length (TTL) of just 11mm, this lens is smaller than standard M12 lenses, making it ideal for space-constrained integrations like thin bezels or compact IoT housings.
Balanced F2.8 Aperture: The F2.8 fixed aperture provides good light handling capabilities while maintaining a sufficient depth of field to keep subjects in focus at varying distances.
