FLUORIT SUPER APOCHROMAT APORIS 2.4/135 Full.MC7 years agoI designed an objective lens using fluorite for a telescope and learned how effective it is for correcting chromatic aberration. Thanks to the kindness of Canon Optoron, it was made available to us. After struggling to design due to the low refractive power of 1.43, which was researched on the brightest 135mm Lens, which can be expected to be the most effective, we adopted the Ernostar type with little Coma, and adopted a large bright fluorite for the first Lens, realizing a bright high-performance lens with an Fno of 2.4.
