Abstract
Overview
ISO 14490-5:2021 - "Optics and photonics - Test methods for telescopic systems - Part 5: Test methods for transmittance" specifies standardized procedures to determine the of telescopic systems and telescopic observational instruments. It defines the measurement principle (ratio of emergent to incident flux), the required test arrangement (radiation source, monochromator/filters, collimator, aperture stop, integrating sphere, detector and signal processing) and the reporting and analysis needed to produce repeatable, traceable transmittance data.
