Marshall - 5 mmf/2 Fixed Lens for M12-mount

Elevate your imaging setup with the Marshall 5 mm f/2 fixed lens designed for M12-mount cameras. This high-performance lens pairs precision glass optics with a rugged, compact aluminum housing to deliver sharp, distortion-free imagery from corner to corner. Whether you’re building a machine-vision system, deploying an industrial surveillance solution, or adding reliable optics to embedded cameras, this fixed focal-length lens offers exceptional image quality, consistent performance, and easy integration. With multiple housing variants—M12, S-Mount, and CS-Mount—you can select the configuration that best fits your sensor size and camera ecosystem while maintaining the same clarity and speed the Marshall line is known for. The design emphasizes reliability and RoHS compliance, ensuring it meets modern environmental and industry standards without sacrificing performance.

• Precision optics for sharp corners and minimal distortion: The 5 mm focal length at f/2 delivers crisp edge-to-edge detail and strong lateral resolution, reducing visual artifacts and ensuring uniform sharpness across the frame for reliable measurements and high-quality surveillance footage.
• Rugged, compact housing: Anodized aluminum construction provides durability in demanding environments while keeping the form factor small enough for space-constrained installations. The robust build protects glass elements and tolerances from dust, vibration, and minor impacts.
• Flexible mounting options: Available in M12-mount, S-Mount, and CS-Mount configurations to fit a wide range of cameras and sensor formats. Choose the interface that aligns with your hardware to simplify integration and minimize the need for adapters.
• Fixed focal length for consistent performance: With no adjustable focus, you get predictable field of view and depth of field across deployments. This makes calibration, alignment, and repeatable imaging easier in production environments and long-run deployments.
• Ready for industrial use: Glass optics, RoHS-compliant materials, and high-performance optical coatings ensure reliable imaging under varying lighting, temperature, and mounting conditions—ideal for machine vision, robotics, and security applications.

How to install Marshall - 5 mmf/2 Fixed Lens for M12-mount

Installing the Marshall fixed lens is designed to be straightforward for quick deployment in a variety of setups. Follow these general steps to ensure a secure, aligned fit and optimal image quality:

Step 1: Identify your camera’s lens interface. Determine whether you are using an M12, S-Mount, or CS-Mount camera, and select the Marshall lens variant that matches that interface. If you have adapters or mounting rings, verify compatibility with your camera body before mounting.

Step 2: Prepare the camera port. Clean the lens mount surface and remove any dust or debris. If your camera uses a protective cap on the lens port, remove it to allow the lens to thread into place smoothly.

Step 3: Align and thread the lens. Gently align the lens threads with the camera mount and begin threading by hand. Do not force the connection; cross-threading can damage both the lens and the camera. Once the threads engage, tighten by hand until snug, then use the camera’s normal mounting hardware or a minimal-tightening routine appropriate to the interface.

Step 4: Secure orientation and verify alignment. After threading, rotate the lens to achieve the desired field of view and alignment relative to the camera. If your application requires precise orientation, use any available locking screws or mounting rings to fix the lens firmly in place without introducing tilt or tilt-induced distortion.

Step 5: Calibrate and test. Power up the camera and capture test images or video. Check for corner sharpness, distortion, and exposure consistency across frames. If needed, adjust the camera’s exposure settings and verify that the fixed lens maintains stable imaging across lighting changes. For CS-Mount variants with adjustable housing, you can make fine mechanical adjustments to alignment if required, then lock the position.

Tip: Because this is a fixed-lens design, ensure you select the correct focal length and mount type for your sensor size and target distance. Using an incorrect combination can yield suboptimal framing or blur. In production environments, establish a standard mounting procedure and document it for repeatable deployments.
