Precision Optical Architecture

 

APO Optical System

Advanced APO optics with integrated flat-field correction elements minimize chromatic aberration and improve edge-to-edge sharpness for clearer views across the entire image.

Glass Elements

  • 2 ED Glass: Minimizes chromatic aberration for more accurate color rendering in high-contrast scenes.

  • 5 Lanthanum Elements: Provides high refractive performance and low dispersion for natural color reproduction.

Eyepiece System

2:1 Zoom Ratio UWA Eyepiece: The aspherical ultra-wide-angle eyepiece maintains a constant 75° apparent field of view throughout the 20-40x zoom range, delivering an immersive viewing experience.

Coating System

  • Fully Multi-Coated (FMC): Reduces Reflections
  • Phase-Correction Coating (PC): Preserves Resolution & Contrast

Together, these advanced coatings deliver ≥91% light transmission while minimizing reflections, enhancing contrast, and preserving true-to-life color.

100mm Objective Lens

Dual ED optics and a built-in hood provide bright, high-resolution views with reduced light interference.

26.5mm Large Eyepiece

A large eyepiece and 3-step metal twist-up eyecup provide lasting comfort during extended observation.

6cm Large Focus Wheel

A large center focus wheel delivers smooth, accurate adjustment with a full focus range in just 2 turns.

Assistant

Find Your Target Faster

The included red dot aiming system makes it easier to find distant subjects and guide others during observation.

IP67

Built for Any Weather

Waterproof and Nitrogen-Purged to prevent internal fogging, ensuring clear views in rain, humidity, and changing environments.
