ISO 18844 Test Chart for Imatest LED Light Sources
The ISO 18844 Flare Test Charts are available Pre-Mounted for use with Imatest LED Light Sources. This chart is a mylar photomask with high-density non-reflective black patches added to minimize reflection. The test chart is mounted on clear acrylic for ease of use with the Imatest LED Light Sources.
To obtain valid measurements, the chart must be photographed in a completely darkened environment. Any reflections on the surface of the chart will invalidate the results.
ISO18844 數字相機圖像眩光測試卡用於鏡頭雜散光/Flare的分析，主要測量耀斑,雜散光；可導入imatest軟件進行結果分析。
