TS EN ISO 14880-1

TS EN ISO 14880-1 is a vocabulary standard for microlens arrays. In micro-optics and optoelectronics, such standards are used to align terminology so that designers, manufacturers, laboratories, and users interpret the same technical terms in the same way. Microlens arrays are optical structures made up of many small lenses arranged in a regular pattern and used to redirect, collect, distribute, or condition light in compact optical systems.

What a microlens array means in technical practice

In general technical terms, a microlens array is a multi-element optical surface in which many miniature lenses operate as a coordinated array rather than as a single lens. That makes concepts such as element pitch, curvature, focal length, fill factor, alignment, and surface profile especially important in design and documentation. Vocabulary standards do not usually prescribe performance targets; instead, they create a shared language that reduces ambiguity across design, manufacturing, metrology, and specification work.

Why the vocabulary matters

The Part 1 designation indicates that this document provides the conceptual foundation for the series. Its practical value is in clarifying terminology before any later parts define measurement methods or other technical topics. Microlens arrays are used in camera modules, sensor optics, beam shaping, illumination control, and other compact optical assemblies. Clear definitions help engineers compare products, write specifications consistently, and interpret related optical documentation with less ambiguity.
