Long Eye Relief (LER) Eyepieces

These multi-coated eyepieces provide a generous 20mm eye relief, and all focal lengths including the 2mm model feature particularly wide diameter eye lenses for maximum viewing comfort. These eyepieces are especially valuable for spectacle wearers, as the long eye relief allows them to view the entire field whilst spectacles are being worn. Rubber eyecups are provided for added comfort and to keep out extraneous light.
