The 11-33x magnification range allows you to smoothly transition from a wider search view to detailed examination of distant objects. The HD optical system with selected low-dispersion glass minimizes chromatic aberration and provides high resolution, clarity across the entire field, and accurate color reproduction. XR Plus illumination and dielectric prism coating maximize light transmission and image brightness, especially in twilight. The housing is argon-filled, waterproof, shockproof, and fog-free, so the device works reliably in the harshest field conditions. The straight design is convenient for eye-level observation and subject tracking, and the integrated Arca-Swiss standard base allows for quick mounting of the tube on a compatible tripod. Weighing in at around 777g and measuring 279mm in length, it is one of the most compact in its class.\u003c\/p\u003e\u003cp\u003e \u003cstrong\u003eAbout the Vortex brand:\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e Vortex Optics (USA) is a leading American brand specializing in the production of high-quality optics for hunting, tactical tasks, nature observation and shooting sports. Today, the company is among the top three world leaders in the field of sports and tactical optics, setting trends for the entire industry. To ensure the highest quality, Vortex produces its flagship lines and top optical elements in high-tech factories in the USA and Japan.\u003c\/p\u003e\u003cp\u003e Features:\u003c\/p\u003e\u003cul\u003e\u003cli\u003e \u003cstrong\u003eZoom 11–33x\u003c\/strong\u003e — continuous change of magnification in the range from 11 to 33 times allows one tube to search for an object in a wider field and to detail it at the maximum. As the magnification increases, the field of view narrows and the brightness decreases, so it is more convenient to start the search with 11x. This makes the device universal for various tasks without changing the optics.\u003c\/li\u003e\u003cli\u003e \u003cstrong\u003e50mm lens\u003c\/strong\u003e - the diameter of the entrance lens determines the amount of light collected and the resolution of the instrument. For a compact class, 50mm provides a good balance between aperture and low weight. This allows the tube to remain mobile, unlike heavier models with 65-85mm lenses.\u003c\/li\u003e\u003cli\u003e \u003cstrong\u003eHD Optical System\u003c\/strong\u003e - The system is built on selected HD low dispersion glass elements that reduce chromatic aberration (color fringing at contrast boundaries). The result is high resolution, edge-to-edge clarity, and accurate color reproduction. This is a key advantage of the Viper HD line over budget tubes.\u003c\/li\u003e\u003cli\u003e \u003cstrong\u003eXR Plus Lens Coatings\u003c\/strong\u003e is a proprietary multi-layer anti-reflective coating applied to all glass-to-air surfaces. It provides maximum light transmission, increasing image brightness and clarity. The effect is especially noticeable at dusk, when every bit of light is important.\u003c\/li\u003e\u003cli\u003e \u003cstrong\u003eDielectric Prism Coatings\u003c\/strong\u003e - Multi-layered reflective coatings on the prism faces increase reflectivity to nearly 99%. This results in bright, clear images with accurate colors. When combined with XR Plus illumination, it maximizes the overall light output of the system.\u003c\/li\u003e\u003cli\u003e \u003cstrong\u003eArmorTek coating\u003c\/strong\u003e is an ultra-hard, scratch-, oil-, and dirt-resistant protective coating on the outer lenses. It makes cleaning the optics easier and protects surfaces from damage in the field, ensuring the tube maintains image quality for a long time.\u003c\/li\u003e\u003cli\u003e \u003cstrong\u003eVariable exit pupil (4.55–1.52 mm)\u003c\/strong\u003e — the diameter of the light beam exiting the eyepiece is equal to the objective lens diameter divided by the magnification. At 11x it is 4.55 mm (50 ÷ 11), and at 33x it decreases to 1.52 mm (50 ÷ 33).
