Abstract: 
Виготовлено та досліджено новий фазовий сповільнювач на основі рідкісної та маловивченої рідкокристалічної фази – кристалічноїсмектичної G-фази, отриманої змішуванням двох сертифікованих нематичних сумішей. Фазовий сповільнювач прозорий у видимій і ближній інфрачервоній частинах оптичного спектру. Температурна стабільність у широкому діапазоні температур, високе двозаломлення та висока міцність дають змогу виготовляти різні типи сповільнювачів фаз, які можна використовувати в оптиці, оптико-хімічному аналізі та поляриметрії.
