<p>An optical magnifier capable of allowing the user to observe an object stereoscopically in an easy position, having a long working distance even if the magnification is large and a long distance from the eyepieces to the eyes, comprising a first auxiliary convex objective (4a) opposed to an object (1), a half mirror (5) for reflecting a pair of right and left beams of light transmitted through the first auxiliary convex objective, a pair of first reflecting members (7L, 7R) for reflecting the beams toward each other, an objective (2) disposed between the pair of first reflecting members, a second reflecting member (9) for reflecting the beams reflected by the pair of first reflecting members twice and transmitted through the objective and the half mirror toward a primary image-forming surface (14), a second auxiliary convex objective (4b) disposed near the second reflecting member and having an image-forming action, and an eyepiece (11) from which the beams passing through the primary image-forming surface emerge.</p> |
