ABSTRACT:
A low magnification, high resolution macroscope. The macroscope includes a body section, a stage for supporting a specimen, and a lens system including an objective lens assembly having a diameter greater than 22 mm. for forming an enlarged, intermediate image of the specimen on the stage. The macroscope also includes an eyepiece for forming a further enlarged, focused image of the specimen. Preferably, the macroscope further includes an illumination system for illuminating the specimen, and this illumination system includes a light source and a mirror. The mirror directs light from the light source, through the objective lens assembly and onto the specimen, and this mirror has a diameter larger than the diameter of the objective lens assembly. With this arrangement, the mirror directs light onto the entire horizontal cross-sectional area of the objective lens assembly, and also the mirror does not restrict the size of the image of the specimen transmitted from the objective lens assembly.
