The 4x Anastigmatic Loupe with One Scale from Peak is designed to allow viewers to simultaneously inspect the entire image area of a film or negative as small as 32 x 45mm (microfilm), or flat objects up to 58mm in diameter. Whereas typical magnifiers only care about the center of the image image, this loupe is manufactured to be critically sharp from edge-to-edge as well as the center.
This loupe has been produced so that you can inspect the whole image field by merely moving your eyeball, without moving your face. This is achieved by placing the effective pupil of the loupe 25mm (1.0") above the upper edge of the loupe. This kind of design enables you to inspect a great number of negs or slides quickly and efficiently. An interchangeable glass scale is included to allow for measurement of objects directly on the film plane. This is included In case what you need is not a whole view of the object but an extended part of the object.
- Insures critical sharpness from edge to edge and corner to corner because of the careful correction of the loupe for optical aberrations
- Part of the barrel is constructed of clear plastic to allow for illumination of opaque objects
