Marshall Electronics V-553.9-5MP-VIS-IR M12 - Mount 3.9mm Fixed Focal Lens

Precision Optics for High-Resolution Imaging
The Marshall Electronics V-553.9-5MP-VIS-IR M12 Lens is engineered to enhance the performance of 5MP cameras equipped with a 1/2" sensor, providing sharp and clear imagery. Featuring a 3.9mm focal length, this lens offers a broad 127.2° diagonal field of view, making it perfect for applications requiring wide-area coverage with fine detail. Its fixed iris design simplifies operation while ensuring consistent exposure settings in varying lighting conditions.

Designed for Superior Infrared Performance
This M12-mount lens is specifically IR-corrected to deliver optimal performance across both visible and infrared spectrums, ensuring flawless image clarity day or night. The IR correction minimizes focus shift in different lighting, which is crucial for maintaining consistent image quality in surveillance, inspection, or any application where precision is key.

Robust Build with Anodized Aluminum Housing
Constructed with anodized aluminum, the V-553.9-5MP-VIS-IR lens is built to withstand the rigors of both indoor and outdoor use. The durable housing protects the lens elements from dust, moisture, and impact, ensuring long-term reliability and performance under challenging environmental conditions.

Advanced Optical Construction
The optical assembly of the V-553.9-5MP-VIS-IR lens comprises eight elements in eight groups, all featuring a SLAR coating that reduces reflectivity to less than 1% across a 400 to 700nm range. This meticulous design significantly enhances image quality by reducing lens flares and ghosting, providing users with exceptionally clear and vibrant images.

Versatility Across Applications
With its ability to handle visible to near-infrared light wavelengths (486.1 to 656.3 / 780, 850nm), this lens is versatile across various light conditions. It’s ideal for applications ranging from general surveillance to specialized industrial tasks where different wavelengths are used to inspect or monitor different materials or processes.
