TAKAHASHI TOA-130NFB ORTHO-APO TRIPLET Focusing motor The reduction of the opticalThe Takahashi TOA 130NFB is an Ortho Apochromatic triplet refractor with the highest possible correction of any refractor on the market. The unique optical configuration based on a highly air spaced triplet completely eliminates spherical aberration while having the best chromatic correction in the Takahashi range. With two S FPL53 ED elements, the air spaced triplet lens cell has a Strehl ratio of 99. 8% at the optimal wavelengths of human vision.
