ガラスびんを落とした際の安全性を確認します：飛散防止性能試験 規格名：jis､日本ガラスびん協会規格 ; ガラスびんの試験例 （4）その他. ガラス製品の比重、透過率、強度（圧縮,引張）、屈折率、耐光性、外観、表示等の試験・検査 The duochrome test involves the projection of black letters or symbols onto a bipartite green (at approximately 535nm) and red (at approximately 620 nm) background . The red and green wavelengths are dioptrically equidistant, approximately 0.25 D, from the yellow wavelength (570 nm). The green wavelength focuses in front of the retina and the Chromatic aberration, the basis of the test, occurs because different wavelengths of light are bent to a different extent.
