FIELD: instrument making.
SUBSTANCE: proposed method comprises transmitting converging monochromatic radiation through optical system made up of radiation source, crossed polarizer and analyzer with tested quartz crystalline lens arranged there between, all above mentioned components being installed serially and perpendicular to system axis. Lens optical axis is aligned with that of optical system to produce interference pattern to judge upon defect of quartz crystalline lens. Lens surface defect presence is revealed by local distortion of radii of rings-isochromats crossed by black Maltese cross, while lens inner defect related with refractivity nonuniformity is revealed by rupture of rings and their displacement relative to the center crossed by Maltese cross.
EFFECT: revealing both surface and inner defects of quartz lens by interference pattern.
