Please note - This eyepiece is Argon-purged; it is not Nitrogen-purged as indicated in the photos above.
Using advanced computer design, combinations of low dispersion and high refractive index optical glasses, and durable multilayer deposition coatings, Explore Scientific 100° Series hyper-wide field eyepieces are optimized to produce high contrast, high resolution, and superior flat field characteristics. And yes, they are indeed ruggedized and waterproof to withstand the outdoor environment.
The visual effect of these eyepieces with their long eye-relief and their 100° apparent field is an extreme full-immersion experience. You have to try it understand the visual impact that these eyepieces produce.
Like all Explore Scientific eyepieces, the lens elements of the 100° eyepiece are meticulously cleaned and aligned before being installed in their precision machined lens barrels.
Each lens and lens grouping have EMD (Enhanced Multilayer Deposition) Coatings and are edge-blackened to eliminate light scatter and maintain image contrast. Contrast is further enhanced with baffles that mask and deflect unwanted stray light.
Each 100° Series Argon-Purged Waterproof eyepiece is internally sealed and purged with inert, dry argon gas to prevent internal fogging, to halt the intrusion of fine particulates and fungus, and to maximize the life of the internal coatings. To make sure, every 100° eyepiece is tested by submerging them down to 1 meter of water for 30 minutes.
Explore Scientific's eyepieces are backed with their exclusive Explore STAR Transferrable Extended Life of the Product Warranty. Limited Warranty is one year, which converts to the Explore STAR Transferrable Extended Life of the Product Warranty when product is registered within 60 days of purchase. We think that you will find Explore Scientific eyepieces rank among the finest obtainable and represent an outstanding value.
In developing their new eyepieces, Explore Scientific has taken a fresh perspective and addressed several points. Their goal was to produce an ultra-wide angle design that provides pride of ownership at a great value:
Focus on Value - Explore Scientific invites direct comparison to any eyepieces on the market in their category.
Protection from the Outdoors - By making the eyepiece body argon-purged and waterproof, eyepiece internal elements will remain as pristine as the day they were assembled. The sealed, dry environment is impervious to internal fogging and contaminants such as fungus growing in between the lens elements. Their 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 they test every eyepiece in one meter of water for 30 minutes.
Creating an Identity - Explore Scientific looks at purchasing fine optical equipment as an investment, and it should be treated as such. With a unique serial number on each eyepiece, they can track when a product was made, and the owner can document their equipment for insurance and warranty purposes.
Providing Peace of Mind - Explore Scientific stands behind their products with the free Explore STAR Transferrable Extended Life of the Product Warranty upon registration of the product. Want to trade or sell your eyepiece? You'll get more value if its remaining warranty can be transferred to the new owner.
