 The low dispersion and high refractive optical glass make the Explore Scientific 100° 30mm Argon-Purged Hyper-wide Field eyepiece remarkable for high contrast and high resolution images as well as producing very flat fields. The eyepiece is tested by submerging it in 1 meter of water for a half an hour!

Since Argon atoms are larger than nitrogen, they don't leak as easily and therefore create a more secure waterproof and moisture resistant design. The inertness of Argon is also better than Nitrogen which prevents more chemical reactions to preserver the internal components of the eyepiece. In addition, Argon conducts less heat therefore keeping a more stable temperature inside the eyepiece.

The eyepiece is designed to work with the Explore Scientific 3" Diagonal.
