Marshall - 5 mmf/2 Fixed Lens for CS Mount

Introducing the Marshall 5 mmf/2 fixed lens for CS Mount, a purpose-built optic engineered for professional surveillance and machine-vision deployments. This compact lens is designed to extract maximum detail from 5MP cameras with a 1/2" sensor while maintaining exceptional image quality across a broad range of lighting conditions. Its IR-corrected optical design preserves sharpness, color fidelity, and contrast from daylight through near-zero light, making it a reliable choice for security systems, broadcast applications, OEM integrations, and precision machine-vision workflows. Built to withstand real-world environments, it delivers consistent performance with low distortion, stable focus, and dependable imaging in demanding installations.

• Three focal lengths in one compact CS-mount lens—3.9mm, 5.0mm, and 7.6mm—to tailor field of view for surveillance, access control, or machine-vision tasks without swapping optics. This flexibility helps you optimize coverage, depth of field, and scene framing for classrooms, corridors, entrances, or industrial lines.
• IR-corrected optics provide high-contrast, true-to-life imagery from visible light into infrared-lit scenes, reducing bloom, glow, and color shifts in low-light conditions. This makes the lens ideal for daytime monitoring and night surveillance where infrared illumination is present or when cameras operate in near-dark environments.
• Compact physical footprint designed for discreet mounting—approximately 1 inch in length and 1.1 inches in diameter—allowing seamless integration into tight camera housings, compact encoders, and compact broadcast or OEM systems without compromising form factor or aesthetics.
• Optimized for 5MP 1/2" sensor optical design, delivering crisp edges, fine textures, and reliable detail across the frame. The lens leverages precision optics to maximize sensor performance, ensuring accurate rendering of faces, license plates, or small object details essential for security monitoring and inspection tasks.
• Durable, versatile solution suitable for a range of professional deployments—from enterprise security and public safety to industrial automation and machine-vision applications—where consistent image quality, reliability, and ease of integration matter most.
