Explore Scientific 25mm 100 Degree Argon-Purged Eyepiece

EPWP10025-01 Explore Scientific 25mm 100 Degree Series Argon-Purged Waterproof Eyepiece

Using advanced computer design, combinations of low dispersion and high refractive index optical glasses, and durable multilayer deposition coatings, Explore Scientific 100 degree Series Argon-Purged Waterproof extreme wide field eyepieces are optimized to produce high contrast, high resolution, and superior flat field characteristics. The visual effect of these eyepieces with their long eye-relief and their 100 degree apparent field is truly a full-immersion experience. The 100 degree Series eyepieces come with a removeable and foldable soft silicone rubber eyecup for the comfort of the observer, and as experienced astronomers know, eye comfort is critical when trying to observe at the visual limits of the telescope.

Protection from the Outdoors - By making the eyepiece body Argon-purged, the waterproof eyepiece internal elements will remain as pristine as the day they were assembled. Argon purged environments are used to protect some of the world's most historic documents, such as the US Constitution. The sealed, dry environment is impervious to internal fogging and contaminants such as fungus growing in between the lens elements. This waterproof eyepiece is easier to clean, and there is no risk of cleaning solution migrating from the top of the lens and seeping around edges to be trapped in between elements. To insure a perfect seal, every eyepiece is tested in one meter of water for 30 minutes.
