Micropositioners Ealing offers three different ranges of manual micropositioners: MicroMech™ (compact size), MiniMech™ (mid-size), and MacroMech™ (large). The selection of the most appropriate range is determined by several key criteria; such as, range of travel, resolution, and reading accuracy. Range of Travel Linear stages provide a wide choice of travel from 6.5 mm with micrometer-driven MicroMech™ stages to 50 mm with micrometer-driven MacroMech™ stages. Resolution or Minimum Incremental Movement This is the smallest controllable movement of a stage (i.e. the smallest movement achievable by hand on thumbscrew or micrometer-driven stages). It is specified individually for each manual micropositioner. When using stages fitted with MotorDrivers™ or EncoderDrivers™, much higher resolutions or smaller movements are achievable using pushbutton control or computer control respectively. Motorization Many of the manual micropositioners can be fitted with either MotorDrivers™ (open-loop dc motor operation) or EncoderDrivers™ (computer controlled closed-loop encoder operation). They simply replace the normal manual micrometer head fitted to the stage. MotorDrivers™ allow remote control of a stage when used in conjunction with a MotorDriver™ control unit and suitable power supply. They can also improve the resolution of a linear stage, resolving 0.1 µm for one press of the control button. EncoderDrivers™ convert a manual stage to a computer-programmable micropositioner capable of sub-micrometer resolution. Up to eight stages with EncoderDrivers™ may be controlled from a PC with one drive card and eight plug-in modules installed. Ealing Catalog, Inc. 3845 Atherton Road. Suite #1. Rocklin.
