Describtion from TMBoptical Itself:
The TMB/APM 14" f/12 triplet air spaced apochromatic lens is the world's
largest production apochromat. Using three specially matched glasses from
Russia's best glass melting factory, and a small spherochromatically
air space, TMB Optical has come up with an apochromat that has superior
correction. The geometric spot sizes from the deep violet to the near
all within the diffraction spot limit, resulting in a color free lens. The
design is nulled
at the peak visual wavelength centered at 555nm in the green-yellow. The
CCD and photographic performance is superb, and coupled with its large
this lens will satisfy the most critical applications.
