Description
Eliminate every blind spot in your imaging architecture with our premium 8MP 1.5mm M12 fixed focal lens. Specifically engineered for high-density sensor formats with a Φ4.5mm image circle, this high-performance fisheye lens delivers an ultra-wide, spherical 185° field of view across all horizontal, vertical, and diagonal axes. Featuring full IR corrected glass optics and a fast F2.5 aperture, it eliminates day/night focus shift to guarantee crisp, 4K-grade 8 Megapixel details under both daytime and active infrared illumination. It is the definitive hardware choice for international engineering teams designing rugged automotive lens systems (360° AVM), panoramic CCTV lens structures, and autonomous drone & UAV lenses.
Product Highlights
- True 185° Spherical View: Captures full hemispherical surroundings in a single frame, replacing multiple conventional narrow cameras to drastically lower system power, bandwidth, and hardware costs.
- Ultra-HD 8MP Resolving Power: Built with premium high-index glass to resolve full 4K details on dense micro-sensors, eliminating peripheral pixel-dropping and edge blurring common in low-end optics.
- Day/Night IR Corrected Tech: Features advanced confocal infrared correction that ensures light paths for both visible and IR spectra focus on the exact same focal plane, preventing night-time focus degradation.
- Fast F2.5 Aperture Performance: Draws in ample light volumes to maximize low-light performance, providing exceptionally clean, noise-free images for nighttime vehicle surround-views and AI surveillance.

Target Applications & Device Compatibility
Core Application Scenarios
This 185° wide angle lens is custom-designed for complete environmental mapping, surround-view automotive safety, and wide-area security tracking. It acts as the core optical element for commercial vehicle Around View Monitoring (AVM) and advanced driver-assistance systems (ADAS), granting 360-degree situational safety to heavy trucks, transit buses, and delivery fleets. Due to its superior 8MP clarity and day/night infrared performance, it excels in top-down single-camera ceiling setups for retail storefronts, open warehouses, smart city traffic junctions, and institutional corridors. Furthermore, its rugged construction makes it highly effective for autonomous drone & UAV lenses navigating tight spaces, as well as panoramic machine vision industrial mapping arrays.
Compatible Device List
- Sensors & Image Blocks: Fully optimized for 1/2.7″, 1/2.8″, and 1/3″ high-density CMOS sensors (such as mainstream Sony IMX and Onsemi 4K/8MP imaging chips).
- Automotive Surround Frameworks: Integrates perfectly into side-mirror pods, front grille housings, and rear bumper backup enclosures connected to multi-channel stitching processors.
- Security & Industrial Systems: Fits standard 360-degree panoramic dome IP cameras, smart city CCTV lens mount setups, and custom industrial lens brackets.
- Customization Services: Supports volume modifications for specialized anti-reflection coatings, hardened outer elements for anti-scratch protection, or customized mechanical threads.
Designed for 360° automotive surround-view and ultra-HD panoramic surveillance applications.
Frequently Asked Questions
Q1: Definition of IR‑corrected fisheye lens
A: It aligns visible and infrared focal planes via coatings and low‑dispersion glass for round‑the‑clock sharp footage.
Q2: Does the Φ4.5‑mm image‑circle lens fit a 1/2.5‑inch sensor
A: Black vignetting rings appear; 1/2.7‑inch or 1/3‑inch sensors deliver complete frameless viewing.
Q3: Meaning of ‑104% fisheye distortion
A: Extreme‑negative distortion enables its 185° field‑of‑view; backend software can straighten the curved picture.
Q4: Suitability for outdoor vehicle and drone installation
A: Its sturdy machined casing works outdoors; an IP67/IP69K housing is suggested for long‑term harsh‑environment use.
Q5: Focus‑adjustment method for the fixed‑focus M12 lens
A: Twist the M12×0.5 lens while previewing live video, then lock sharp focus with lock‑ring or thread adhesive.
Q6: Custom‑made infrared filter options
A: Our certified factory supplies OEM lenses with custom IR coatings or filter‑free set‑ups for your lighting needs.
