The Vixen corrector PH is a 3-element Wynne corrector for demanding applications. Designed for the Vixen R200SS Newtonian reflector, but also suitable for other optics with similar specifications.
The optical design consists of 3 lenses in 3 groups . The corrector provides excellent correction of system-induced coma of parabolic mirrors and the resulting spherical aberration. The corrected field has a diameter of 44 mm , making it suitable for the 24x36 mm format (full-frame DSLR/CCD cameras) . This guarantees razor-shape images across the entire field. The lens surfaces are coated with a cutting-edge 99.9% anti-reflective AS coating , which is also used for Vixen's flagship VSD100F3.8.
