TeleVue Delos 1.25", 3.5mm eyepiece

Introducing a line of mid-to-short focal length eyepieces boasting a generous 20mm eye relief and an expansive 72° apparent field of view. Every detail, from optical precision to mechanical and ergonomic design, has been meticulously reconsidered to achieve a reference-standard performance suitable for any visual application.

The Delos series was conceived as a refinement of the broader field Ethos line. By narrowing the field to 72°, we gained the flexibility to enhance eye relief while effectively managing pupil aberrations, all without compromising on the size of the eyepiece. Leveraging the performance benchmarks set by Ethos, the Delos design ensures full field sharpness, virtually perfect distortion correction, and outstanding color neutrality. This is made possible through the integration of glass-matched multi-coatings and anti-reflection surfaces throughout the eyepiece.

Further enhancing contrast is our newly introduced continuously adjustable height eyeguard system, capable of locking into any desired position. With the eye-lens measuring a substantial 35mm in diameter, preventing stray light reflections and minimizing extraneous light significantly enhances perceived contrast. The sliding action of the eyeguard enables precise positioning of the soft rubber eyeguard to cater to individual observer preferences. Convenient indicator marks on the eyepiece body provide reference points for achieving the perfect position. Additionally, the eyeguard is designed to rotate for users of Dioptrx.
