ISO 14490-8:2011 describes test methods for determining the performance of night-vision devices as specified in ISO 21094.

Abstract

Overview - ISO 14490-8:2011 (Test methods for night-vision devices)

ISO 14490-8:2011 is part of the ISO 14490 series on optics and optical instruments. It defines standardized (NVDs) as specified in . The standard specifies laboratory conditions, test arrangements, measurement sequences and assessment criteria for objective evaluation of NVD characteristics used in telescopic systems and image-intensifier-based equipment.

Key topics and technical requirements

The standard covers a comprehensive set of test methods and requirements, including:

Environmental and test conditions: recommended ambient temperature (20.0 ± 5.0 °C), relative humidity (40–60 %), allowed variation during tests (±2 °C and ±4 %), and recommended dark-room illuminance (0.01 lx to 0.04 lx).
Power and illumination: use of a dedicated power supply (external supply acceptable within ±0.1 V), incandescent lamp sources with filament colour temperature (2 856 ± 50) K for certain measurements, and lamp voltage stability limits (≤ 0.3 %).
Measurement scope: standardized methods for measuring magnification (including variable magnification), night-vision device gain, angular field of view, exit pupil diameter and eye relief, dioptre zero-position error, image rotation, non-parallelism of emerging ray bundles, limit of resolution, working resolution and range of vision, close distance of observation, imperfections in the field of view, and continuous work time.
Test arrangements and procedures: detailed requirements for collimators, scales, reticles, telescope read-outs and other optical test rigs, including scale dimensions, line widths relative to resolution, and required read-out accuracy.
Reporting and repeatability: assessment of results and repeatability to be stated in accordance with ISO 5725-1, and systematic error to be evaluated analytically or by inter-laboratory comparison.

Practical applications

ISO 14490-8 provides the objective measurement framework used for:

Product development and optical design validation of night-vision goggles, scopes and imaging modules.
Production quality control and acceptance testing for manufacturers.
Independent laboratory testing and type-approval for defense, law enforcement and security procurement.
Comparative benchmarking of NVD performance (resolution, gain, field of view, ergonomics like eye relief).

Who uses this standard

Optical and photonics engineers, test laboratory personnel, and quality managers in NVD manufacturing.
Military and security procurement officers and certification bodies specifying performance requirements.
R&D teams developing image intensifier modules, night-vision scopes and augmented night optics.
