The SurgiTel Compact Prisms Loupes are available in the magnification powers of 3.5X, 4.5X, and 5.5X. Each compact prism loupe is custom-manufactured for each clinician's pupil measurements, facial profile, and working distance. Some of the significant features of these loupes are the expanded field of view, flexible depth of field, and overall lightweight feel. Compared with other traditional prism loupes, SurgiTel's Compact Prism Loupes are considerably smaller in size, and therefore, lighter in weight. Visually, the field of view is expanded and the depth of field allows clinicians flexibility while working. An added feature with the SurgiTel Compact Prism loupes is the Working Distance Adjustment Caps. These caps can accommodate a focal range adjustment or extension conveniently.
