Explore Scientific has used a combination of low dispersion and high refractive index optical glasses with multi-layer EMD coatings to produce high contrast, high resolution, and superior flat-field characteristics.
Each of the Explore Scientific 82° Series Argon-Purged Waterproof eyepieces is tested in one meter of water for 30 minutes, to guarantee a quality seal, and thus ensure fogless, moldless viewing for a lifetime.
All components, including internal pieces are purged in argon for further protection. Argon, as compared to Nitrogen for example, is more inert to chemical reactions, impervious to water and is less susceptible to rapid temperature fluctuations, meaning that the eyepiece performs better and is more durable.
Also, the piece has a removable and foldable soft silicone rubber eyecup for the comfort of the viewer and ease of cleaning.
