Optimized KAHLES AMV coatings realize nearly loss-free transmission in the critical spectral range of light (about 520 nanometers). This allows to extract the very smallest reserves of light during the lowest light shooting conditions.Complex optical designsComplex optical designs with up to four objective lenses creates an unprecedented distortion-free image with an extremely wide, edge-defined field-of-view.HousingExtremely durable housing machined by state-of-the art production methods from a single piece of high-grade material. Extremely precise adjustment mechanism creates absolute repeatability.OcularWide angle ocular with safe eye relief optimized for excellent viewing comfort and quick acquisition. Robust etched glass reticle in second image plane does not change size with increased magnification. A decisive advantage at a long distance for the long shot.
