Abstract:
A portable magnifying instrument useful for colposcopy is provided which may include in combination an optical system capable of providing a distortion free clear continuously varying 10× to 15× magnification of a three-dimensional wide object; an integrated energy efficient, low powered and intensity controlled illumination system; a power pack and mounting. The optical system may have an eyepiece lens system and an objective lens system. The illumination system may have a plurality of light emitting diodes (LEDs) connected to the power pack; mounted in such a manner that the angle between the LEDs is maintained with respect to the optical axis of the lens system and that the light beam from the said LEDs impinges on the wide object to be observed at the focus of the said lens system.
