This is my Nikon CFI 10X PLAN Achromat Infinity Corrected Microscope Objective Lens which I have used for macro photography with my Nikon Bellows - listed separately. It is in In perfect condition having had little use from new. I will include a number of adapter rings which I used to attach to a Raynox DCR250 and the Nikon bellows to use as a tube lens. Appropriate step up / down rings. 25mm thread Pattern for Nikon Eclipse Microscopes.
Nikon is one of the big names in microscopy, and has a vast range of microscopes and objectives which includes the Nikon CFI Plan 10x/0.25NA 10.5mm WD Objective, ideal for extreme macro focus stacking in the 5:1-10:1 range. The biggest single advantage of this optic is not image resolution or sharpness, but the allround package with a longer than average working distance.
It is not a Mitutoya 10x which is a scale beyond other 10x objectives, but it is a decent allround performer that can reliably be expected to give a very decent level of performance. Nikon CFI Plan 10x/0.25NA 10.5mmWD objective, material no. Shown with its outer brown casing, which I actually usually just remove to give a little more room for light to make its way down to the specimen. This Nikon 10x CFI plan achromat is not only outstanding at 10:1 with a 200mm tube lens on APSC, but because it has such a nice large image area it can also be a wickedly sharp 5:1 with a 100mm tube lens.
