ABSTRACT:
An enlarging apparatus includes a base with an upright post and a housing supported on the post above the base. An optical system in the housing includes a vertically adjustable, downwardly facing concave mirror having its focal point adjacent the base and a semi-transparent mirror arranged along and inclined with respect to the optical axis of the concave mirror. Light beams from an object supported on the base pass through the semi-transparent mirror, are reflected by the concave mirror, and are then reflected by the semi-transparent mirror. A binocular telescope is supported on the housing in alignment with the path of the beams reflected by the semi-transparent mirror.
