TS Optics 2x Barlow lens 1.25″
Want to get more out of your telescope and favourite eyepieces without investing in a whole new eyepiece set? The TS Optics 2x Barlow lens in 1.25″ format is a proven and practical solution that instantly doubles the magnification of any eyepiece - with no visible loss of image quality. It is one of the most useful accessories an astronomer can have in their observing bag.
Optics and coatings
The TS Optics Barlow lens features full multi-coated (FMC) anti-reflection layers on all optical surfaces, ensuring maximum light transmission and minimising unwanted reflections. Blackened lens edges further suppress scattered light inside the barrel, resulting in images with excellent contrast and sharpness. For demanding observers working with planetary details, double stars or lunar surface features, contrast and sharpness are precisely what determine how much you actually see at the eyepiece.
Wide compatibility with 1.25″ eyepieces
The large aperture of the Barlow lens element allows trouble-free use even with long focal length eyepieces in the standard 1.25″ size. There is no risk of the light cone being clipped or vignetted - even with comfortable wide-field eyepieces with a large exit pupil, you get a full and sharp image across the entire field of view.
How the Barlow lens works
The Barlow lens simply slides between the eyepiece and the telescope focuser. Its negative lens element extends the effective focal length of the telescope by a factor of two, which means double the magnification for any eyepiece you are currently using. An important practical benefit: the eye relief of the eyepiece remains unchanged, so observing comfort is just as good as when using the eyepiece directly. This is especially appreciated during long observing sessions.
