Designed to seamlessly integrate with their TSN-99, TSN-880, and TSN-770 Prominar spotting scopes, the Kowa TE-80XW 40x Extreme Wide-Angle Eyepiece delivers crisp and clear views with an exceptional 80° field of view that makes viewing and digiscoping through it a unique and immersive experience.

Optical Performance

  • Exceptional 80° apparent angle of view presents an expansive visual experience to take in the entire landscape without having to pan the scope
  • The wide field of view is ideal for digiscoping because you will not experience vignetting when using a smartphone or camera
  • Fixed 40x power when used in the TSN-99, 35x with the TSN-880 & TSN-770
  • Extremely low-dispersion glass virtually eliminates chromatic aberration across the entire field of view for improved resolution, clarity, and color rendition
  • Integrated field-flattener lens eliminates lens curvature to give you clear views from edge-to-edge without distortion
  • Proprietary KR coating on the exterior of the lens actively repels dirt, moisture, and dust from collecting on its surface to ensure clear views
  • 117.5-foot field of view at 1000 yards with the TSN-99, 135.5 feet with TSN-880 & TSN-770

Use and Handling

  • Compatible with current Kowa System accessories including adapters for digiscoping and a 1.6x extender
  • Twist-up eyecup for easy and comfortable viewing with and without eyewear
  • Long 17mm eye relief presents a generous eye box to reduce eye strain during long glassing sessions
  • O-ring sealed to be waterproof
