Low-cost vehicle cameras use a variety of mounting and alignment techniques for the camera lens in relation to the imager. One of these methods is adhesive mounting with a UV-curable glue, which allows the lens to be focussed before the adhesive is fully cured.
Other methods for focusing the lens include using PCB mounting and focusing Screws, dropping the lens barrel onto the imager’s surface, adhering the lens directly to the imager with adhesive, integrating the lens barrel and camera lens holder, and focusing the lens by adjusting the front and back housings of the camera.
The resolution of the lens can be adjusted to meet the human contrast sensitivity function, and optical chromatic aberration can be replaced with digital chromatic aberration to reduce costs.
The lens barrel is attached to the lens holder by an adhesive, and the adhesive is designed to provide at least a selected strength of bond between the lens and lens holder when exposed to at least one selected operating condition for a selected period of time.
The adhesive is sufficiently curable by UV light to support the lens relative to the lens holder, and it is further curable to a fully cured strength when exposed to a secondary curing step.
The Global car-mounted camera lens Polycarbonate Resin market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Two new hybrid lenses for autonomous driving have been unveiled by LG Innotek, a branch of the LG Group that specialises in electrical components.
The lenses, which come in two varieties, combine thin plastic and glass to improve performance while reducing size and raising price parity.
In-vehicle driver monitoring systems (DMS) will require one kind of lens, whereas larger ADAS applications will require a different kind of lens.
According to the division, both are 20% to 30% thinner than glass-only equivalents, and their design strategy enables them to function consistently, irrespective of temperature, and correctly identify objects.
By enabling more sensors to be placed into other body sections, including the front fillers, LG Innotek hopes to increase the range of sensor design with their hybrid lenses.
