Home Eyepieces Explore Scientific Eyepieces Explore Scientific 9mm 100 degree Argon purged Eyepiece
This 9mm eyepiece has a 100 degree Apparent Field Of View and the body of the eyepiece is purged and waterproof preserving the internal elements to 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 the eyepiece is tested in one meter of water for 30 minutes. The eyepiece features EMD (Enhanced Multilayer Deposition) Coatings.Focal Length: 9mm2" barrelAFOV: 100 degreesPurged and Waterproof: Submersible to 1 meter for 30 minutes; Internally sealed and purged with inert, dry nitrogen gas to prevent internal foggingBody: Anodized Black Aluminum; Laser-Etched Description and Serial Number;Rubber Grip: Internally O-Ring SealedBarrel: Stainless-Steel, 2-inch, Double Taper, Accepts Standard 2-inch Filters
