HEINE Keyhole loupes
For apertures from Ø 0.3 mm. Working distance from 5-250mm.

Keyhole loupe The unique construction of HEINE multi-purpose keyhole loupes enables you to view through a 0.3 mm aperture and into narrow cavities, e.g. a security lock. They provide excellent results when used as illuminated loupes for various working distances.
How it operates: Light from a XHL Xenon Halogen bulb [1] is condensed and projected [2] onto a mirror [3], which reflects it through 90°. The examiner moves the instrument as close as possible to the object to be examined and looks over the top edge of the mirror. A lens wheel [4] is located directly in front of the mirror and incorporates a ring of 17 lenses of various focal lengths. By turning this lens wheel, the examiner selects a lens [5] which provides a sharply-focused, magnified image. The focal length can be varied during the entire examination.
  • Gives a bright, illuminated view in even the smallest cavities, openings, bores, locks, jets, cylinders etc.
  • Up to 10x magnification. You can inspect through openings as small as 0.3 mm! Can also be used as an illuminated loupe for surface examination. XHL Xenon Halogen illumination.
  • Can be focused by selecting any one of 17 lenses on the lenswheel.
