Plano-Concave Lens
Plano-concave lenses diverge parallel light and have negative focal length and spherical aberration, allowing correction of other lenses' aberrations, spherical aberration, coma and distortion. The side generally faces the distant object or infinity, as stated in the source. One surface is flat with infinite radius, the other concave with positive or negative radius depending on sign convention.

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.
A laser bar is an array semiconductor laser chip integrated with dozens of emitters, which realizes hundred-watt quasi-continuous output on a single chip. With regular emitter arrangement and controllable fill factor, integrated thermal design and superior wall-plug efficiency compared to single chips, it acts as the core light source for high-power pumping, medical lasers and precision processing.
