SV213 3x Barlow lens adopts 3-element apochromatic design, which can effectively solve the problems of chromatic aberration and vignetting. All three lenses are FMC coated for clear and bright images. SV213 3-element 3x Barlow lens has 3x magnification. When viewing with a low-power eyepiece, the SV213 provides the field of view of a high-power eyepiece with a comfortable exit pupil distance.
