The SVBONY SV136 3× Barlow Lens (1.25″) is a high-quality achromatic Barlow designed to increase magnification while maintaining image sharpness and contrast. By tripling the effective focal length of your eyepieces, it allows you to achieve higher magnifications without sacrificing optical performance.

• 3× magnification factor triples the power of any 1.25″ eyepiece
• Achromatic optical design for improved sharpness and colour correction
• Optimised for fast telescopes and short focal ratios
• Standard 1.25″ barrel compatible with most eyepieces
• Secure brass compression screw for stable eyepiece holding
• Supplied with dust caps to protect optics when not in use

Achromatic Optics for Clear, High-Power Views

The SV136 uses an achromatic lens system to minimise chromatic aberration and maintain image clarity at higher magnifications. This makes it especially useful for lunar and planetary observation, where sharpness and contrast are critical.

Triple Your Eyepiece Collection

By inserting the SV136 3× Barlow between your telescope and eyepiece, you instantly triple the magnification of your existing eyepieces. For example, a 10mm eyepiece effectively becomes a 3.3mm, allowing you to reach higher powers without purchasing additional short-focal-length eyepieces.

Ideal for Fast Optical Systems

This Barlow lens is well suited to fast telescopes with short focal ratios, where it can improve effective focal length while helping to maintain image quality. It is particularly useful with refractors, Dobsonians, and Schmidt-Cassegrain telescopes using 1.25″ accessories.

Secure, User-Friendly Design

A solid metal body and secure set screw ensure that eyepieces remain firmly in place during use. Protective dust caps are included to keep the optics clean during storage and transport, making the SV136 a reliable addition to any observing kit.
