laser scanning confocal microscope
Quick Summary
A laser-scanning confocal microscope (LSCM) is an advanced optical instrument that creates detailed, sharply defined images of biological specimens. It works by focusing a laser beam to a single point on the specimen and detecting light only from that focal plane through a pinhole. This process eliminates out-of-focus light, allowing for clear visualization of fine, three-dimensional structures. By scanning the laser across the specimen and collecting a series of images at different focal depths (a Z-series), a complete 3D image can be reconstructed. LSCMs are crucial in biological research, especially when specimens are stained with fluorescent dyes that emit light under the laser's excitation.1
