Explore Scientific Ultra-wide Angle 100 Series 9mm Eyepiece 2.0" Barrel -

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 Nitrogen-Purged Waterproof eyepiece is internally sealed and purged with inert, dry nitrogen 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. Each and every Explore Scientific eyepiece is inspected both at the factory and again at their USA facility in California.
Developing the new eyepieces Explore Scientific wanted to take a fresh perspective and address several points. The goal was to produce an ultra-wide angle design that providespride 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 nitrogen-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.
The 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 we test every eyepiece in one meter of water for 30 minutes.
Creating an Identity - We look at purchasing fine optical equipment as an investment, and it should be treated as such. With a unique serial number on each eyepiece we 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 a free 5 Year Transferrable Limited 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.
