Type segmentation categorizes ADAS lenses according to optical construction and spectral response, directly influencing design cost and integration complexity. The primary sub‑type is the visible‑spectrum lens, typically built on glass or high‑index polymer, which dominates approximately 55 % of total shipments because it supports mainstream camera‑based functions such as lane‑keeping and forward‑collision detection. Infrared (IR) lenses, engineered for thermal imaging, account for roughly 20 % of the market, driven by night‑vision and pedestrian‑recognition modules that require sensitivity beyond the visible band. Polarizing lenses, which mitigate glare and enhance contrast, represent about 12 % of demand, primarily in high‑glare environments like automotive head‑on‑lighting. Wide‑angle lenses, offering fields of view between 120° and 180°, contribute 8 % as they enable comprehensive scene capture for surround‑view systems. Finally, telephoto lenses, with focal lengths exceeding 12 mm, occupy the remaining 5 % and are reserved for long‑range object detection in advanced adaptive cruise control. Collectively, these type categories structure the ADAS Lens market size by aligning optical capability with vehicle‑level functional requirements.
