A novel series of field microscopes, which are designed for use in locations remote from conventional power sources or for in-lab use, are described. The enabling technology is the illuminator which is described in several embodiments which cover brightfield transmitted light, brightfield reflected light, darkfield transmitted light and darkfield reflected light as well as uni-directional oblique and slit-ultra illumination techniques. The light sources are modular so that they can be interchanged on the microscope, and they feature ultralow power and current consumption, integral dimming control, battery power and light weight. Optically the illuminators offer extremely flat field illumination along with excellent colour correction or selectable narrow wavelengths. The illuminators are characterised by high optical efficiency and small size. The microscope includes a novel focussing drive with torque limiting nature, a novel method of attaching the objectives, a novel mounting scheme to take advantage of existing camera tripods and novel adapters for film, video and digital cameras. A novel hydraulic fine focus drive is also discussed.
