Abstract: To provide binocular loupes capable of ensuring an optimal focal distance for a user using a simple operation, focus adjustment units disposed in eyepiece units of a pair of left and right loupe bodies of binocular loupes are provided with focus adjustment lenses, and holding rings having magnetic bodies into which the focus adjustment lenses are fitted. The holding rings are mounted in contact with correction lenses constituting optical systems inside the loupe bodies, are drawn and held by magnet rings. By this means, it is possible to readily replace the focus adjustment lenses by mounting the lenses detachably from the loupe bodies, and it is possible to ensure an optimal focal distance.

Abstract: Provided are binocular loupes capable of ensuring an optimal focal distance at the time of focusing for a user using a simple operation. A focus adjustment unit disposed in the eyepiece units of a pair of left and right loupe bodies of binocular loupes is provided with a focus adjustment lens and a magnet ring. The magnet ring is mounted in contact with a corrective lens constituting an optical system inside the loupe bodies and is secured by a holding ring. The focus adjustment lens has a magnetic body at the peripheral edge drawn to the magnet and is fitted into and held by an annular ring of the magnetic ring. The focal adjustment lens can thereby be detachably mounted on the loupe bodies.
