Product description
Explore Scientific’s 62° eyepieces not only offer exceptional edge definition, even with fast optics and a large visual field, but their large pupillary distances also make it possible to view the entire visual field, even when wearing glasses. Fatigue resulting from awkward neck angles and strenuous observation does not set in thanks to these eyepieces’ exceptional viewing properties.
Thanks to its argon gas filling, internal fogging is effectively prevented, and there is no need to worry about dust, lens fungus or cleaning fluids inflitrating. The eyepieces are fitted with a watertight seal. This guarantees many years of unquantifiable observation joy using these high-quality eyepieces.
Further features:
- Patented EMD tempering for maximum contrast
- Carefully blackened lens edges to avoid reflections
- Stainless steel sleeve with conical safety groove
The abbreviation “LER” stands for long eye relief , meaning large pupillary distance. These eyepieces are ideally suited to glasses wearers!
