Sažetak
Our ability to perform visual tasks depends on how our eyes perceive the details
of the task. Magnification loupes rely on light refraction through lenses. The Keplerian telescope has
a converging lens eyepiece and the Galilean telescope a diverging lens eyepiece. The size of the image
when viewing through the lenses depends on the level of magnification. Dental loupes are available with
magnification powers from around 2.5x and some go up to even 6.0x. Telescope glasses are made with
optical barrels, carrier lenses and carrier frames. Important quality factors for the lenses are resolution,
field of view, depth of field, optical aperture and weight of the telescope system.
Dental loupes with magnification powers ranging from 3.5x to 5.0x are ideal for dental procedures
requiring high levels of precision and accuracy. The loupes make it easier to navigate the oral cavity
clearly and examine every essential part of the gums and teeth during dental check up. By providing a
magnified view of the operating field, clinical works become easier, more efficient and safer.
