Education
Loupe Research Library
This guide turns a common loupe buying question into a practical checklist, then connects the reader to the right HeliosX model and measurement resources.
Built for clinicians researching surgical and dental loupes.
01
Start with the work
The procedure mix determines the optics. Start with specialty, wear time, posture, and expected magnification before choosing a model.
02
Magnification changes by specialty
A 2004 peer-reviewed survey of 148 specialists and senior trainees in the west of Scotland (Jarrett, Microsurgery 2004) found clear specialty patterns in intraoperative magnification use. Plastic, maxillofacial, ophthalmic, and otolaryngology surgeons reported frequent use of magnification, cardiothoracic and pediatric surgeons leaned heavily on loupes, and neurosurgery was more microscope-centered.

03
Use the HeliosX model map
Medusa and Apollo are ergonomic prismatic systems. Galileo and Newton are lightweight affordable systems. Kepler is the high-magnification system.
