The SVBONY SV216 1.25″ 3× Barlow Lens is a premium optical amplifier designed for high-magnification planetary, lunar, and double-star observation. Its advanced 4-element optical design delivers noticeably higher contrast, improved edge sharpness, and better colour correction than standard 2-element Barlows.

• True 3× magnification for detailed planetary and lunar observation
• 4-element optical system for improved sharpness and contrast
• Fully multi-coated lenses maximise light transmission
• Edge-blackened optics reduce internal reflections and scatter
• Preserves eye relief for comfortable high-power viewing
• Standard 1.25″ barrel compatible with most eyepieces

High-Contrast Planetary Performance

The SV216 uses a 4-element / 3-group optical layout to minimise chromatic aberration and light scatter, producing clean planetary edges and high contrast. This makes it particularly effective for observing Jupiter, Saturn, Mars, the Moon, and resolving fine surface detail.

Designed for Visual Use & Astrophotography

Unlike simple Barlow lenses, the SV216 maintains eye relief when used with longer focal-length eyepieces, making high magnification more comfortable. Its stable optical geometry also makes it well suited to planetary imaging and lunar photography.

Secure Mechanical Design

The precision-machined aluminium body features a brass compression ring and three coaxial thumb screws, ensuring excellent optical alignment and secure eyepiece holding without barrel damage. An integrated M28.5 × 0.6 filter thread allows the use of standard 1.25″ filters.
