POL SERIES
ROUTINE and RESEARCH LAB POLARIZING MICROSCOPE
Polarized light microscopy Mikroskop cahaya terpolarisasi adalah teknik mikroskop optik yang melibatkan cahaya terpolarisasi. Teknik sederhana termasuk pencahayaan sampel dengan cahaya terpolarisasi. Cahaya yang langsung ditransmisikan atau datang dapat, secara opsional, diblokir dengan polariser yang berorientasi pada 90 derajat ke pencahayaan. Teknik pencahayaan ini paling umum digunakan pada sampel birefringent di mana cahaya terpolarisasi berinteraksi kuat dengan sampel dan karenanya menghasilkan kontras dengan latar belakang. Mikroskop cahaya terpolarisasi digunakan secara luas dalam mineralogi optik.
