Technical Details
Loupes. They are over 50% lighter than our flip up Models, weighing less than 2oz. Since the
loupes will be on your nose for 4-8 hours a day, you want something as light as possible.

Feather Series Prismatic Loupes also has 25% wider field of view than flip up models, making
it much easier to get used to. You will be amazed to see how clear and bright the images are.

4.0 x is the most popular prismatic model among the entry level user of these powerful Loupes.
It offers the widest field of view and the most generous depth of field among its class. And it is
the easiest prismatic Loupe to use. If you have never used Prismatic Loupes before, we
recommend you start with this model.
Measuring Working Distance

Selecting the optimum working distance will
ensure that you maintain the correct
ergonomic posture and focal distance. We
offer a choice of four working distances.

To calculate your specific working distance,
measure the distance between your eyes
and the patients teeth while maintaining an
ergonomic position.
