FIELD: optical instruments. SUBSTANCE: device is designed as lens, which consists of liquid and absorbs control beam. In addition device has control beam source, mirror and tray. Mirror reflects controlled beam at angle of 45 degrees and passes controlling beam or reflects controlling beam and passes controlled beam. Body of lens is generated by controlling beam in thin layer of non-volatile material with positive tension response in volatile solvent with addition of paint that absorbs controlling beam. EFFECT: decreased size, increased tuning range for lens focus length, contactless control of position and automatic centering of lens body. 2 dwg
