NEO Achromatic Refractor Optical Tube Assemblies.

Chromatic aderration of achromatic refractors increases as their aper-ture increases.This becomes especially apparent for achromatic refractors with short focal length (less than F8) with apertures lager than 120mm. To compensate for this, Vixen's "NEO Achromatic" refractor has an additional two-element objective lens behind the primary objective lens, to give a bright image with excellent color correction compared to conventional achromatic refractors. As a result, star images are reduced less than 60 microns in size at the edge of field of view.
