Microscopes with focus lock

Focus lock

— possibility to block the focus mechanism of the microscope. One way to use this feature is to work with numerous the same type of specimens: by blocking the focused microscope, you can change specimens without wasting time focus at each change. In addition, blocking will not interfere when working at very high magnifications (from 1000x and higher). Focus on such magnifications must be very precise, and the working distance is small — as a result, accidentally hitting the coarse focus knob, you can thoroughly knock down the settings or even “drive” the lens into the preparation. Blocking helps to avoid such troubles.
