APM 2x Barlow Lens 2″

APM Barlow 2”

This is the 2″ counterpart of our famed 1.25″, 2x/1.5x Barlow lens. It is well made both in design and craftmanship. Both lenses are fully multicoated for best-possible contrast and transmission. The lenses have a diameter of 37mm, thus you can even use 2″ wide angle eyepieces without vignetting.

Further uses:

With a 2″ extension tube – 50mm – you will attain a magnification of 2.7x compared to an eyepiece without the Barlow lens. That way you turn a 30mm wide angle eyepiece into an 11mm wide angle eyepiece with comfortable eye relief.

Remove the black anodized lens cell from the Barlow lens and screw it directly into your eyepiece to attain a magnification of 1.5x.
