Phase contrast microscope

Vedclass · Answer

(D) $Phase \ contrast \ microscope$ is specifically designed to observe living,unstained cells in motion. It converts phase shifts in light passing through a transparent specimen into brightness changes in the image. Since living cells are often transparent and do not require staining (which would kill them),this microscope allows for the detailed observation of their shape and movement in real-time. Electron microscopes require the specimen to be dead and dehydrated,making them unsuitable for observing motion.
