PROCESS DETERMINING REFRACTIVE INDEX OF OPTICAL MATERIAL |
摘要 |
FIELD: optics. SUBSTANCE: process determining refractive index of optical material includes following operations: Sample is painted with luminescent pigment, one of butts as minimum is left unpainted. Painted surface is illuminated with light with spectrum of absorption of luminophor. Area of spots at fixed distances one from another is determined. Aperture angle is found from geometric constructions and refractive index is determined from formula <EMI ID=0.363 HE=9 WI=15 TI=CHI>. EFFECT: possibility of measurement of refractive index of thick films. 1 dwg
