Eyepiece Explore Scientific 68° Ar 16mm (1.25")

Eyepiece Explore Scientific 68° Ar 16mm (1.25")

• Water resistant, Argon purged and dust sealed
• Large, sharp 68° field of view
• EMD multi-coating with blackened edges
• All eyepieces of this series are parfocal

With the introduction of the 68° Series we are pleased to make two important improvements in eyepiece manufacturing, the first being the 15-layer Enhanced Multi-Layer Deposition (EMD™) coatings on all glass-to-air surfaces for maximum contrast, and the sealing of the eyepiece with the use of Argon gas purging instead of the standard Nitrogen gas. While nitrogen is a good choice that will last for many years, argon is a larger molecule that maintains its protective properties over a wider range of temperatures and is even more resistant to diffusion, further extending the waterproof protective environment of the eyepiece body.

Through computer-optimized design, careful selection of optical glasses, and enhanced multilayer deposition coatings, the Explore Scientific 68° Series™ eyepieces produce great eye relief and ensure high image correction, flat field, and high contrast across the entire image field. An excellent choice for those who perform prolonged visual studies of details with subtle variations in brightness, and for those who must wear glasses while observing.

All 68° Series eyepieces are fully EMD (Enhanced Multi-Layer Deposition) coated and edge-blackened to produce superior contrast.
