1. Product Overview and Market Positioning

This high-performance optical module represents the pinnacle of modern ultra-wide-angle imaging technology, specifically engineered for next-generation machine vision, autonomous navigation, and professional surveillance applications. At its core, the lens delivers an exceptional 12-megapixel resolution paired with a massive 160-degree diagonal field of view (DFOV), effectively bridging the gap between immersive spatial awareness and critical detail retention. Unlike conventional wide-angle lenses that sacrifice edge clarity for breadth, this 8G+IR optical assembly is precision-tuned to maintain high modulation transfer function (MTF) performance across the entire image circle. The product is designed to serve as a primary sensor for AI-driven perception systems where situational context is as vital as target identification. Its compact form factor and extreme environmental resilience make it a versatile solution for integration into drones, robotic platforms, automotive ADAS, and ruggedized industrial inspection equipment. By combining a large 1/1.7-inch sensor format with advanced optical engineering, this module sets a new benchmark for what is achievable in sub-30-gram optical assemblies, offering system integrators a drop-in upgrade path for existing vision pipelines without requiring mechanical redesigns.

2. Optical Architecture and Design Philosophy

The optical design is built upon a sophisticated 8-element glass and plastic hybrid configuration (8G+IR), meticulously arranged to manage the complex light paths inherent in a 160-degree field of view. Each element serves a specific corrective function: front elements handle extreme ray angles and barrel distortion control, while rear elements focus on flattening the field curvature and correcting chromatic aberrations. The inclusion of IR-corrected optics ensures that focal shift between visible and near-infrared spectra is minimized, enabling consistent sharpness in day-night switching applications without mechanical refocusing. The 3.20mm effective focal length (EFL) was selected as the optimal balance between angular coverage and pixel density on a 1/1.7" sensor, providing sufficient ground sample distance for object classification at range while maintaining peripheral awareness. The F/2.0 maximum aperture is achieved through high-precision aspheric surfaces that reduce spherical aberration typically associated with fast ultra-wide designs. This aperture size not only enhances low-light signal-to-noise ratio but also allows for faster shutter speeds in dynamic scenes, reducing motion blur in high-speed robotics or vehicular applications. Every air-glass interface features multi-layer broadband anti-reflection coatings optimized for the 400-1000nm spectrum, maximizing transmission efficiency and minimizing ghosting from internal reflections.

3. Resolution and Sensor Compatibility Specifications

Supporting 12 megapixels on a 1/1.7-inch format translates to approximately 4000 x 3000 active pixels, demanding optical resolution exceeding 200 line pairs per millimeter (lp/mm) at the center and maintaining >120 lp/mm at 0.8 image height. This specification ensures the lens fully resolves modern backside-illuminated CMOS sensors with pixel pitches down to 1.4µm. The large sensor format provides significant advantages over smaller alternatives: improved dynamic range, better low-light sensitivity due to larger photosite area, and reduced diffraction limitations at the F/2.0 operating point. The lens projection is designed to cover the full 1/1.7" diagonal with minimal vignetting (<1.5 stops at full aperture), ensuring uniform illumination for both human viewing and algorithmic processing. Compatibility extends to popular sensor platforms including Sony IMX series, OmniVision OS12D, and Raspberry Pi HQ/AI camera modules, with standardized C/CS-mount or M12x0.5 threading options available upon request. The optical design accounts for sensor cover glass thickness and microlens stack characteristics, ensuring optimal performance when matched with recommended sensor partners. For system integrators, detailed Zemax/Code V black box models and spot diagram data are available under NDA to facilitate virtual prototyping and tolerance analysis before physical sampling.

4. Field of View and Geometric Characteristics

The 160° DFOV / 131° HFOV / 99° VFOV specification places this lens in the fisheye category, utilizing equidistant projection mapping to preserve angular linearity across the frame. This projection type is preferred for machine vision applications because it maintains a constant degrees-per-pixel ratio, simplifying geometric calibration and 3D reconstruction algorithms. The -64% distortion value is an intentional optical trade-off: rather than optically correcting barrel distortion (which would require additional elements, increase weight, and reduce transmission), the design embraces predictable distortion that can be precisely modeled and corrected in software. This approach preserves edge resolution and reduces total system cost. The vertical FOV of 99° is particularly valuable for ground-based robots and dashcams, providing adequate sky-to-ground coverage without excessive ceiling or road surface capture. For panoramic stitching applications, the lens's rotational symmetry and consistent distortion profile enable seamless multi-camera array calibration. Detailed distortion lookup tables and polynomial coefficients are provided with each unit, enabling real-time dewarping on embedded GPUs or dedicated ISP hardware. Users should note that effective resolution after software rectification will vary by region; center regions retain near-native 12MP detail, while extreme periphery may experience interpolation-dependent softening typical of all fisheye correction workflows.

5. Aperture Performance and Low-Light Capabilities

The F/2.0 aperture represents a significant light-gathering advantage, transmitting 2x more photons than F/2.8 alternatives and 4x more than F/4.0 designs. In practical terms, this enables usable imagery at 0.1 lux illumination levels when paired with high-sensitivity sensors, extending operational windows into dusk/dawn and indoor low-light scenarios without supplemental lighting. The iris mechanism (if equipped with adjustable variant) maintains circular bokeh characteristics throughout the aperture range, avoiding polygonal artifacts that can confuse feature-matching algorithms. Even at full aperture, corner relative illumination exceeds 40%, ensuring peripheral regions remain above noise floor thresholds in dark environments. The 8G+IR construction specifically addresses longitudinal chromatic aberration at wide apertures, preventing color fringing that degrades edge detection accuracy. For night-vision applications using 850nm or 940nm IR illuminators, the lens maintains parfocal performance within ±0.02mm focus shift, eliminating the need for dual-lens day/night systems. Thermal defocus compensation is integrated into the optical design, ensuring F/2.0 performance remains stable across the -40°C to +105°C operating range without active refocusing. This passive athermalization is critical for unattended deployments where maintenance access is limited or impossible.

6. Mechanical Design and Integration Guidelines
