Automotive Lens Applications

Core Application Scenes

This 48MP automotive lens is designed for vehicle camera systems where high image resolution, wide scene coverage, and accurate optical alignment are important.

Its 120° diagonal field of view on a 1/2″ sensor provides extensive visual coverage for cameras positioned around the vehicle. This makes the lens suitable for applications that need to capture nearby objects, surrounding vehicles, road edges, obstacles, and other elements within a broad viewing area.

The lens is particularly relevant to compact automotive camera modules used for:

• Advanced driver assistance camera systems
• Surround-view and multi-camera vehicle imaging
• Front-view and side-view automotive cameras
• Rear-view and parking camera modules
• Vehicle perception cameras
• Cabin and exterior automotive vision systems
• Low-profile automotive camera assemblies

The Active Alignment (AA) capability is an important advantage for automotive camera manufacturing. Precise alignment of the optical axis relative to the image sensor can help control optical performance during module assembly, which is particularly relevant to high-resolution imaging systems where small alignment errors can affect image quality.

Designed for high-resolution automotive camera applications requiring wide scene coverage, compact optical dimensions, and precise active alignment.

High-Resolution Automotive Optical Design

The combination of 48MP resolution and wide-angle imaging makes this lens suitable for automotive camera designs where image detail and scene coverage must be considered together.

At a 1/2″ sensor format, the lens provides a 120° diagonal, 101° horizontal, and 82° vertical FOV. With a 1/2.3″ sensor, the corresponding FOV is 116° diagonal, 99° horizontal, and 80° vertical.

The different FOV specifications allow optical engineers to evaluate the lens against the actual image sensor used in the camera module. Sensor selection is especially important in high-resolution automotive applications because sensor size, pixel structure, image circle, and lens performance all affect the final imaging result.

For a better understanding of sensor and lens matching, see Towin’s Sensor Guide.

Active Alignment for Automotive Camera Modules

One of the defining characteristics of this product is Active Alignment (AA).

Unlike a simple passive mechanical mounting process, active alignment can be used during camera module assembly to optimize the relative position of the lens and image sensor based on actual optical performance. This is particularly valuable for high-resolution automotive cameras, where optical alignment becomes increasingly important as image resolution increases.

The lens also features an 8.8mm TTL and 1.415mm BFL, providing a compact optical layout for automotive camera housings with restricted mechanical space.
