Vortex Spotting Scope – Razor HD 11-33-x50

Vortex Spotting Scope – Razor HD 11-33-x50

The Vortex Spotting Scope – Razor HD 11-33-x50 features high-quality glass with specialized optical coatings to provide clear and bright images. The triplet apochromatic lens elements are made of High Density (HD) Extra-low Dispersion (ED) glass to increase light transmission, minimize distortion and virtually eliminate chromatic aberration. All air-to-glass surfaces have Vortex’s XR anti-reflective coatings to minimize light loss. Additionally, they are ArmorTek coated for scratch resistance. To ensure accurate color across the entire visible spectrum, the Porro prisms are dielectric coated. These coatings are highly reflective and lose less than 1% of the light that passes through them. The use of Porro prisms creates a better depth of view over roof prisms. This combination of coatings and optics creates a spotting scope that produces bright, clear, highly contrasted images with accurate color transmission.

The lightweight magnesium-alloy body is o-ring sealed and argon-filled to be water and fogproof. A dual focus system features a coarse fast-focus and a fine-focus wheel. The scope has a tripod mounting shoe that also accepts a ¼”-20 mounting bolt. For comfort and convenience, the tripod collar rotates to permit it the eyepiece to be put in the best viewing position. A retractable lens shade keeps the Sun or rain off the objective lens.
