About this product

Lessons learned from the tremendously successful Ethos project were applied to develop this long eye-relief 72° apparent field of view eyepiece line.

Concept: It was natural to take lessons learned from the tremendously successful Ethos project and apply them going forward. In the fall of 2008, Paul Dellechiaie was tasked to investigate a long eye-relief eyepiece design in the 70° AFOV range, retaining the key performance goals met with Ethos. My father named Paul's design "Delos." Delos is a beautiful Greek island which happens to be the mythical birthplace of Apollo, the god of light. More importantly, the name was chosen to recognise Paul, the principal designer of both Delos and Ethos. — David Nagler

Introducing Delos

Tele Vue is pleased to introduce the Delos, mid-to-short focal length line of 20mm eye-relief, 72° apparent field of view eyepieces. Every optical, mechanical, and ergonomic aspect was rethought to achieve reference-standard performance for any visual application.

The Delos was conceived as a narrower field Ethos. Reducing the field to 72° allowed the freedom to increase eye-relief while controlling pupil aberrations without making the eyepiece too large. With Ethos performance standards as benchmarks, the Delos design achieves full field sharpness, virtually perfect f θ (theta) distortion mapping, and colour neutrality. Image fidelity is maximised by utilising glass-matched multi-coatings and anti-reflection surfaces throughout the eyepiece.

Contrast is further enhanced with a new, continuously adjustable height eyeguard system that can be locked in any position. Since the Delos eye-lens measures a relatively large 35mm diameter, preventing stray light from reflecting off the first surface and extraneous light from entering your eye increases perceived contrast. The eyeguard's sliding action allows for positioning the soft rubber eyeguard at the ideal height to suit the observer's preference. Indicator marks on the eyepiece body are handy reference guides for setting your perfect position. The eye-guard can also rotate for Dioptrx users.
