환등기 투사용 암석 · 광물 박편꽂이 마운트의 제작 및 활용하여
A mount consists of two polarizing films at intervals of 2∼3㎜ and a rotatable thin-section holder inserted between two films. The mount is held into a slide projector. We can investigate and study optical characters of rocks and minerals by the projected figures in the same way as the polarizing microscope.
