BS PD IEC TS 62989:2018 encompasses key characteristics of primary optical elements (lenses andmirrors) and lens or mirror parquets for concentrator photovoltaics including: opticalperformance, mechanical geometry, mechanical strength, materials, and surface morphology.The document identifies the essential characteristics, the corresponding quantities of interest,and provides a method for measurement of each quantity.This document allows lens and mirror manufacturers, concentrator module manufacturers,test laboratories and other interested parties to define lens/mirror qualities and inspect lensesand mirrors. There are no pass/fail criteria associated with the document.This document defines the test conditions rather than to specify the precise setup of ameasurement apparatus. For example, this enables laboratories to acquire reliable andcomparable measurement results irrespective of the existing large variety of experimentalsetups for focal spot characterization. High priority is given to comparable and reproduciblemeasurements of the irradiance distribution in the focal plane and of the optical efficiency.This requires trade-offs that reduce the similarities to outdoor conditions. Furthermore, it isintended not to refer to properties of specific solar cells as this document is dedicated toconcentrator optics.The terms for lenses are applicable for mirrors, unless otherwise specified.Cross References:CIE S 014-4/E:2007IEC 60050-845IEC 62788-1-4ISO 10110-7 CIE S 014-2/E:2006IEC 60904-3ISO 11664-1ISO 11664-2CIE S 014-1/E:2006ISO 11664-4ISO 291ISO 10303-21ISO 14782 ISO 10110-8:2010ISO 10110-1:2006IEC 62108:2007ISO 10110-19:2015ISO 489:1999ISO 13468-2IEC 60904-9-1IEC 62899-201ASTM D7490ISO 15184:2012ISO 2039-1:2001 Ed 3ISO 7619-1:2010ASTM D3363 - 05ASTM E424 - 71(2007)ISO 9385:1990 (R10)
