BTX Eyepiece

$2,769.00

Fully compatible with all versions of their ATX and STX spotting scope systems, Swarovski Optik's BTX 30x/35x Eyepiece Module represents the pinnacle of comfort for long-duration glassing sessions. The innovative design replaces the conventional single eyepiece with a dual-eyepiece binocular configuration that enables users to view with both eyes open, and with the eyepieces set at a 45° angle to the optical tube, their head is put in a natural viewing position. When mounted on the 65mm and 85mm models it has a 30x magnification, whereas the 95mm version is stepped up to 35x. Both models have a 63° wide apparent angle of view. To match the performance of the objective modules, this eyepiece module has the SWAROVISION system to improve color fidelity, contrast, and clarity; and SWAROCLEAN coatings help keep the lenses clear and easy to clean.

Optical Performance

  • Dual identical eyepieces
  • 65/85mm Objective: 30x magnification with 65mm/85mm objective models; 35x magnification with 95mm model
  • Proprietary SWAROVISION system improves image contrast, color, and clarity
  • Wide Apparent Angle of View: 63° 
  • Field of View at 1000 Yards: 114' (65mm) / 111' (85mm) / 96' (95mm)
  • Exit Pupil: 2.2mm (65mm) / 2.9mm (85mm) / 2.7mm (95mm)
  • Long, 21mm eye relief on all models

SWAROVISION System

  • High-definition (HD) fluoride glass lenses eliminate chromatic aberrations for accurate color fidelity, and improved resolution and contrast
  • Field-flattener lenses correct spherical aberrations for distortion-free views, especially at the edges
  • SWAROTOP anti-reflective multi-coating that enhances light transmission
  • SWARODUR coatings provide enhanced scratch resistance
  • Non-stick SWAROCLEAN coatings on exposed lens surfaces ensure that water, dirt, sap, and oil can be easily removed without scratching or leaving residue

Use and Handling

  • Provides comfortable both-eyes-open viewing, with reduced, fatigue during long-duration observation sessions
  • Eyepieces set at 45° angle to optical tube for comfortable viewing while sitting, standing, or lying prone
  • Forehead rest improves viewing stability, is adjustable for optimal eye relief and viewing comfort, and is removable if preferred
  • Innovative aiming aid utilizes an unmagnified view with a sunburst-type reticle to find subjects faster and easier than using the angled eyepieces
  • 56-72mm interpupillary adjustment range
  • ±4 right-eye dioptric correction
  • Multi-position twist-up rubber eyecups offer comfortable use with or without eyewear
  • Simple bayonet mount for fast installation and removal
