Applications & Target Devices
This 5MP M12 industrial lens is purpose-built for high-accuracy environments where image warping causes system errors. Its 73° diagonal field of view and F3.5 aperture provide a perfectly balanced mid-wide perspective, making it exceptional for document scanning, barcode reading, and factory automation assembly lines. The built-in IR cut filter efficiently isolates infrared glare, ensuring accurate color rendering in changing industrial lighting or outdoor daylight. Measuring just 15.59mm T.T.L., it allows engineers to design slim, lightweight imaging modules without risking thermal drift or alignment loss during continuous operation.

Designed for machine vision, factory automation, and ultra-low distortion scanning applications.
Frequently Asked Questions
Q: Why is a distortion rate of <-0.2% important for machine vision?
A: In machine vision and FA lens applications, software relies on straight pixels to measure objects or read barcodes. A distortion under -0.2% means lines stay straight, preventing measurement errors and saving CPU processing power since no digital correction is needed.
Q: Can this 1/4″ format lens be mounted on a 1/3″ sensor?
A: No. This lens is specifically tailored for 1/4″ image formats. Mounting it on a larger 1/3″ or 1/2.8″ sensor will cause heavy vignetting and dark corners around the image frame.
Q: What are the advantages of the 2G2P+IRF structure?
A: The 2 Glass + 2 Plastic elements structure provides high resolution and controls chromatic aberration effectively while keeping production costs optimized. The built-in IR Filter (IRF) blocks infrared wavelengths above 650nm to ensure natural daytime color performance.
Q: Is the iris or focus adjustable on this lens?
A: This is a Fixed Focal Lens with a Fixed Iris (F3.5). The focus can be adjusted mechanically during installation by rotating the lens within the M12 mount thread, then locking it with a lock ring.
Q: Does this lens support macro imaging or close-up inspection?
A: The Minimum Object Distance (M.O.D.) is 0.3 meters. It is highly optimized for clear imaging from 30cm to infinity, making it ideal for desktop document scanners, biometric terminals, and assembly line scanning.
Q: Do you support customization for different IR pass filters or modified mounts?
A: Yes. We offer comprehensive OEM/ODM services. We can replace the standard IR filter with an 850nm/940nm bandpass filter for infrared nighttime illumination or adjust mechanical specifications for large-volume orders.
