GPO SPECTRA 10x42 Binoculars

The all-new SPECTRA model is a slight variation of the PASSION ED binocular. Both products are built to the highest 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's is made with high transmission glass, while PASSION's are is made with premium low dispersion ED glass. However, both are optically and technically brilliant.

*PLEASE NOTE: GPO products ship directly from the manufacturer, so please allow extra time for delivery when placing your order.

*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.
