Description Technical Specs
 
Vixen's Barlow lens is placed immediately before an eyepiece to effectively decrease the eyepiece's focal length by the amount of the Barlow Lens divergence. Since the  magnification provided by a telescope and eyepiece is equal to the telescope's focal length divided by the eyepiece's focal length, this has the effect of increasing the magnification of the image. The barlow lens doubles the magnification of any eyepiece. The amount of magnification is one more than the distance between the Barlow lens and the eyepiece lens, when the distance is measured in units of the focal length of the Barlow lens. Designed for telescopes with fast  focal ratio.
