Описание (английский):

This document specifies methods for testing optical properties, other than wavefront aberrations[1] of microlenses in microlens arrays. It is applicable to microlens arrays with very small lenses formed on one or more surfaces of a common substrate and to graded-index microlenses.

Overview

EN ISO 14880-3:2024 (CEN endorsement of ISO 14880-3:2024) defines standardized test methods for optical properties of microlenses in microlens arrays other than wavefront aberrations. It applies to arrays of very small lenses formed on one or more surfaces of a common substrate and to graded‑index microlenses. This second edition updates and replaces the 2006 version and is intended for adoption by CEN member bodies.

Key topics and technical requirements

Scope and exclusions

Specifies tests for optical parameters other than wavefront aberrations (those are covered in ISO 14880‑2).
Applicable to substrate-mounted and graded‑index microlenses.

Substrate testing

Requires quantification of substrate optical quality in accordance with ISO 10110‑5 (surface form tolerances).

Microscope test method

Principle: locate the microlens surface optically and determine the effective back/front focal length by measuring the axial displacement to the focal position.
Details on measurement arrangement, test equipment and general setup.

Measured parameters

Effective focal length (back/front)
Chromatic aberration
Uniformity of focal spot positions
Coupling efficiency and imaging quality (discussed and reported)

Procedure, results and uncertainty

Step‑by‑step measurement procedures, reporting requirements and considerations for measurement uncertainty.

Informative annexes

Annex A: use of wavefront measuring/interferometric systems (alternative techniques)
Annex B: confocal measurement of effective focal length
Annex C: coupling efficiency and imaging quality guidance
Annex D: measurement of focal spot positions using Shack–Hartmann techniques

Documentation

Required content for a comprehensive test report.

Applications

Quality control and acceptance testing of microlens arrays used in:

3D displays and near‑eye optics
Arrayed light‑source coupling and photodetector interfaces
Enhanced LCD backlighting and imaging sensors
Optical interconnects and parallel optical processors

R&D validation of graded‑index microlenses and micro‑optics prototypes

Characterization of focal spot uniformity and coupling efficiency for system integration
