Abstract: Systems and techniques relating to a microscope including a cord retractor. A microscope includes a base, a support arm attached to and extending upwardly from the base and a head attached to the support arm. The head includes at least one lens, and an eyepiece is attached to the head and in optical communication with the lens. A stage is positioned between the head and the base. The microscope further includes at least one electrically-powered component, and an electrical cord electrically connected to the at least one electrically-powered component. A cord retractor is positioned within the base, the cord retractor configured to retract at least a portion of the electrical cord into the cord retractor.

Abstract: Systems and techniques relating to a microscope with an adjustable stage are described. A microscope includes a base, a support arm attached to and extending upwardly from the base, a head attached to the support arm, the head including a lens, and an eyepiece attached to the head. A stage is releasably attachable to the support arm between the head and the base at multiple locations, providing multiple working distances between a lower surface of the head and an upper surface of the stage. When the stage is attached to the support arm at a location, a working distance between the lower surface of the head and the upper surface of the stage is further adjustable to an either greater or lesser working distance. In another embodiment, microscopic and macroscopic viewing can both be provided using a lens changer with multiple lens positioned radially about an axis of rotation.

Abstract: Systems and techniques relating to a microscope storage unit. In one implementation, a storage unit includes a base, a top and multiple receptacles configured between the base and the top. Each receptacle is configured to house a microscope. The storage unit includes multiple charging devices, where each charging device is configured to recharge a battery of a battery-powered microscope. An electrical cord can be electrically connected to the multiple charging devices, and include a plug configured to mate with an electrical outlet to supply electrical power to the charging devices. One or more wheels can be connected to a lower surface of the base.
