Abstract

A novel illuminator for a field microscope, which takes the place of the condenser and the light source and collimating optics in a traditional microscope, is described. The illuminator is described in several embodiments which cover bright-field transmitted light, bright-field reflected light, dark-field transmitted light and dark-field 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 ultra-low 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 characterized by high optical efficiency and small size.
