SPECTRA 8×42 Binocular


Out of stock

The SPECTRA™ 8×42 is a slight variation to the PASSION™ ED 8×42 binocular. Both products are built to our high German standards, both providing excellent light transmission, color contrast and image resolution. The difference between SPECTRA™ and ED™ binoculars is the type of glass used for the front objective lens. SPECTRA binoculars’ front objective lens is made with high transmission glass, the PASSION™ ED’s front objective lens is made with premium extra low dispersion ED glass. However, both are optically and technically brilliant.

  • High-transmission glass
  • Magnesium micro-bridge and body
  • GPObright™ lens coating technology
  • Lightweight and compact
  • Waterproof, fog proof, and shockproof
  • Tough aluminium eyecup tubes
  • Custom-molded hard case


GPObright is a proprietary coating process that maximizes light transmission through each surface of an optical element. As light hits an optical surface, normal uncoated high-performance glass can reflect up to 5% of that light, redirecting this light so it does not transmit through the optical system. However, when these high-performance lenses are vacuum-coated with GPObright lens coatings, up to 99.7% of the available light passes through each optical surface. Furthermore, when every surface of the entire optical system is properly coated, total light transmission can reach up to more than 92%, making the optical image of a GPO binocular or riflescope “bright,” even in the lowest light conditions.
