FIELD: measurement technology. SUBSTANCE: uneven-armed interferometer to test to toric surfaces includes laser, beam expander, beam splitter, flat reference mirror, observation system, lens and compensator comprising one or two cylindrical lenses positioned in unparalleled path of rays. Compensator is positioned in diverging bundle of rays and two cylindrical lenses of compensator are mounted for turn about optical axis in opposite directions through equal angles. EFFECT: formation of toric wave front. 4 dwg
