Досліджено оптичні властивості тонких плівок сульфіду кадмію, отриманих термічним випаровуванням у вакуумі. Використовували стехіометричні склади бінарної сполуки, попередньо синтезовані з високочистих порошків вихідних компонентів. Плівки різної товщини, нанесені на скляну підкладку, досліджували за допомогою скануючої електронної мікроскопії та визначали коефіцієнт поглинання методом Свейнпола. Встановлено, що зі збільшенням товщини плівки поверхневі утворення зменшуються і при товщині 1 мкм поверхня плівки є суцільною. Визначено, що тонкі плівки сульфіду кадмію мають оптимальні оптичні параметри для використання їх як буферний шар фотоелектричних пристроїв. Усі отримані плівки, крім плівки товщиною 1215 нм, демонструють звичайну інтерференційну картину в спектрах відбиття.
