Medical disposable‑device manufacturers have long demanded high‑performance interconnect accessories for single‑use equipment. The newly‑launched REDEL‑P disposable‑connector family addresses this requirement and delivers premium‑grade electrical connections for varied one‑time‑use medical instruments.
A microlens array (MLA) is a high-precision optical component composed of hundreds or thousands of tiny, uniformly arranged micro lenses on a single flat substrate. Unlike traditional single lenses that focus one light beam, a microlens array can split, homogenize, and reshape light on a micro scale. It is widely paired with VCSELs, lasers, and image sensors, becoming a core part of modern miniature optical systems.
