Description
Empower your optical scanning and smart auditing systems with our high-precision 5MP 2.98mm M12 Ultra Low Distortion Lens. Expertly optimized for 1/3″ image sensors, this advanced wide angle lens delivers an expansive 88° diagonal field of view while keeping optical distortion strictly under 1%. Featuring an ultra-compact Φ14×13.27mm miniature structure and a rigid 4-element (4E) optical layout, it guarantees pristine 5 Megapixel resolving power without edge blurring. It is the premier hardware choice for tier-one global developers integrating compact machine vision, industrial FA, and intelligent CCTV lens modules.
Product Highlights
- Sub-1% Ultra-Low Distortion: Corrects the typical bending associated with wide-angle layouts, providing edge-to-edge rectilinear images that completely remove the need for software de-warping overhead.
- 5MP Resolving Clarity on 1/3″ Sensors: Delivers high-contrast, razor-sharp 5 Megapixel spatial detail, allowing automated inspection setups to read minuscule markers or serial prints without pixel drops.
- Ultra-Short Micro Footprint (13.27mm TTL): Features a minuscule total length and a Φ14mm diameter, sliding seamlessly into tight machine compartments, robotic eyes, and ultra-thin handheld terminal electronics.
- Precision-Crafted 4E Optical Alignment: Utilizes a streamlined 4-element all-surface optical build to ensure high thermal resilience and robust structural stability across variable operating factory temperatures.

Target Applications & Device Compatibility
Core Application Scenarios
This low distortion M12 lens is engineered exclusively for automated geometric measuring and high-speed data capture in space-constrained industrial ecosystems. Its wide 88° angle and near-zero distortion make it highly effective for QR/2D code conveyor readers, automated document scanners, passport validation kiosks, and PCB electronic assembly alignment systems where measuring accuracy is crucial. Additionally, its compact micro housing allows for rapid integration into commercial facial recognition turnstiles, medical micro-imaging arrays, warehouse sorting AGV sensors, and specialized mini CCTV lens housings operating under controlled environments.
Compatible Device List
- Sensors & Image ICs: Tailored for 1/3″, 1/4″, and smaller standard CMOS formats (including mainstream Onsemi, OmniVision, and Sony 5MP/2MP image modules).
- Industrial Automation Kits: Perfectly matches smart inspection cameras, machine vision inspection heads, and custom FA lens mount plates.
- Smart Commercial Terminals: Fits flush inside automated teller machines (ATMs), point-of-sale retail terminals, and smart home entry video modules.
- Customization Inquiries: Available with tailored optical coatings, specific infrared cut filter specifications (e.g., dual-band pass filters), or customized mechanical barrel lengths.
Designed for high-precision barcode scanning and compact machine vision applications.
Frequently Asked Questions
Q: Why is an ultra-low distortion rating under 1% vital for this wide-angle lens?
A: Standard 2.98mm wide-angle optics usually distort or warp the outer edges of an image, turning straight edges into curved lines. By reducing distortion to less than 1%, this lens ensures accurate tracking data for AI scanning engines and biometric recognition algorithms, cutting out processor-heavy software adjustments.
Q: Can this 1/3″ format lens be deployed on a 1/2.7″ or larger image sensor?
A: No, it is not recommended. This optic is designed to illuminate a 1/3″ image circle. Mounting it onto a larger sensor (like a 1/2.5″ or 1/2.7″) will cut off light at the corners, creating heavy dark borders or a “vignetting” effect.
Q: Is the focus adjustable, or is it completely set from the factory?
A: This is a fixed focal lens with a standard M12 thread. To adjust the focus for your specific distance requirements, simply thread the lens into or out of your camera module’s mount holder until your image is sharp, then secure it with a standard locking ring.
Q: What are the benefits of the F3.5 aperture compared to a wider F2.0 option?
A: While an F2.0 lens lets in more light, an F3.5 aperture provides a much wider Depth of Field (DoF). This means objects across a broader range of distances stay sharply in focus at the same time—making it excellent for scanning varied package sizes on high-speed conveyor belts.
Q: What quality assurance documentation do you provide for industrial procurement?
A: Our production lines strictly adhere to ISO9001 and RoHS standards. Bulk‑order buyers get full quality docs: MTF charts, compliance forms and third‑party certificates for easy customs clearance.
